This study develops polyester modified polypropylene (PP) with disperse dye dyeability. The thermal properties, rheological properties, and spectral properties are used for validation and differential analysis. The optimum PP dyeable particle process uses polyester as the mixed copolymer. The melt temperature of polyester material is significantly different from PP, which may lead to a failure of the mixing process. Therefore, this study aims to develop low-melting co-polyester. Different proportions of adipic acid are used in the co-polyester molecular chain to reduce the melting point. The melting point has been controlled successfully, the thermal properties of the modified ester pellet are discussed, and the functional group is then verified by Fourier infrared spectroscopy. Afterwards, the low-melting co-polyester and PP are made into a composite through a dual-screw mixing process with PP grafting maleic anhydride compatilizer. The PP is endued with the dyeability of disperse dye through the molecular behavior of the co-polyester chain segment. The optimum process parameters of the made material are designed by using the Taguchi method, gray relational analysis, and fuzzy C means clustering algorithm, aiming at two quality characteristics: dyeing power and melt index (MI). The results show that the MI of the pure PP polymer is 35.78 g/10 min and the color strength is 100 K/S, while the MI of the PP/co-polyester is 37.63 g/10 min and the color strength is 211.20 K/S. The results suggest that the developed polymer exhibits good processing in circulation and color strength.

“…While the Taguchi method is mainly used for optimizing single quality property (Kuo et al 2013;Kuo and Lan 2014;Zainal et al 2013), optimal processing parameters that determine the single quality do not represent the optimization of process parameters for the overall quality. For this reason, Taguchi method should be combined with other methods.…”

This study designed and optimized the system parameters for a photovoltaic thermal system (PV/thermal system) combined with reflectors. Moreover, it discussed the gain of electrical efficiency and thermal efficiency on the system after adding two reflectors on each of the south and north sides, and adjusting the water circulation system. As the rising angle and position of the sun varies each season, in order to make this study more rigorous, experiments were conducted in four seasons of a year. The Taguchi orthogonal array was used for experimental planning, and the optimal parameters were analyzed for electrical efficiency and thermal efficiency. The analysis of variance was conducted to examine the influential parameters, and principal component analysis was used to calculate the principal component point of each experiment. The results were employed to construct a response surface methodology model. Finally, the steepest descent method was applied to obtain the optimal parameters. The reflector theory was applied to calculate the gain of solar radiation amount after installing the reflector. Moreover, the gain was inputted into the simulation software TRNSYS to simulate the electrical power output and the water temperature in the water storage tank. The confirmatory experiments of the four seasons found that the electrical energy after installing the reflector increased by 0.117-0.183 kWh, and the thermal energy increased by 1.7-2.6 • C. The experiment confirmed that the prediction error was <4 %.Keywords Photovoltaic/thermal (PV/T) · Reflector · Taguchi method · Analysis of variance (ANOVA) · Principal component analysis (PCA) · Response surface methodology (RSM) · Steepest descent method (SDM) · Transient system simulation tool (TRNSYS) List of symbolsP Total generated electrical energy during the day (kWh) G Total solar radiation energy during the day (J/m 2 ) A Module dimension (m 2 ) V m PV voltage at maximum power point (V) I m PV current at maximum power point (A) Q Total generated thermal energy during the day (J) V Water mass flow rate (kg/s) C p Water specific heat (4.18 kJ/kg • C) T f Water final temperature ( • C) T i Water initial temperature ( • C) A r1_a Actual receivable area of upper reflector (m 2 ) W 1 Upper plate width (m) W 1 Upper plate reflect to module width (m) L 1 Upper plate reflect to module height (m) L 1 Upper plate height (m) A r1 Reflection area of upper reflector (m 2 ) 123 J Intell Manuf θ Included angle between reflector and azimuth ( • C) A r2_a Actual receivable area of lower reflector (m 2 ) W 2 Lower plate width (m) W 2 Lower plate reflect to module width (m) L 2 Lower plate height (m) L 2 Lower plate reflect to module height (m) A r 2Reflection area of lower reflector (m 2 ) G r1_c Reflection solar radiation of upper plate (J/m 2 ) G r1Receiving solar radiation of upper reflector (J/m 2 ) L 1Upper plate reflect to module lengthen width (m) G r2_c Reflection solar radiation of lower plate (J/m 2 ) G r2Receiving solar radiation of lower reflector (J/m 2 )

physics, and engineering. One of the key points lies in the development of flexible substrate materials and efficient packaging technology. The components of organic light-emitting devices (OLEDs) or organic photovoltaics (OPV), including the cathode materials and photoelectric conversion layer, are reactive; thus, thin films should encapsulate both the top and bottom surfaces of the devices to realize the desired property. [2-4] Barrier-coated plastic lids, ultrathin glasses, and vacuumdeposited thin films have been developed as thin-film encapsulation (TFE) approaches. [5] However, there are many issues with the current manufacturing methods for encapsulation films. The laser lift-off (LLO) process is widely used for flexible electronics manufacturing, requires evaporating each functional layer onto a substrate, then peeling the devices off the substrate using a laser; the product yield is high, but the productivity is low. In contrast, roll-to-roll (R2R) processing, which involves directly assembling the devices on a formed substrate, is more suitable for large-scale industrial production. [6,7] There are demanding performance requirements for the encapsulation film, such as light transmittance, flexibility, gas impermeability, and heat resistance. The encapsulation film in the direction of light transmission should be highly transparent. [8,9] The other functional layers in electronic devices can be fabricated with nanoscale thickness; thus, the flexibility of the completed devices mainly depends on the properties of the encapsulation materials. Encapsulation materials have gradually developed from rigid glass plates to flexible thin films in recent years. [6,10] The degree of gas permeability is the most important property of TFE materials because flexible electronics use reactive metals and organic matters in devices. It is generally required that the water vapor transmission rate (WVTR) and oxygen transmission rate (OTR) should be on the order of 10 −3-10 −6 g m −2 day −1 to provide flexible electronics to have a sufficient service life. [11,12] Furthermore, OLEDs, for example, use thin-film transistors (TFTs) to control brightness and grayscale. A flat/smooth surface (roughness average R a < 1 nm) is beneficial for the fabrication of its nanostructures, and as the manufacturing temperature of TFTs is very high, A good packing of flexible electronics is one of the most critical points to ensure its lifetime. However, efficient and straightforward packaging technology is still very challenging. In this work, a new strategy for preparing encapsulation film is reported by "enameling" a fusible glass layer on a polymer membrane. Careful consideration has been given to the materials properties and manufacturing process, and the obtained glass-coated polymer can combine the advantageous properties of polymers and inorganic materials unconventionally. The encapsulation films show exceptional overall properties, including transparency (<5% optical deterioration), flexibility (radius of curvature: 1.5 mm), and low ...
