“…From the analysis of GPC, EuTT exhibited depolymerization ability and the PLA was degraded. The degradation of PLA resulted in the decrease in MS and the increase in MI for the PLA/PBAT/EuTT blends . However, the decrease of MS reduces the processing temperature of materials, and the increase of MI will improve fluidity of melt, which is beneficial to the processing of materials.…”

Rare earth europium(III) complex with α‐thenoyltrifluoroacetone and triphenylphosphine oxide (Eu (TTA)3(TPPO)2, shortened as EuTT) was synthesized in this paper, then blended with polylactide (PLA) and poly(butylene adipate‐co‐terephthalate) (PBAT) to prepare the biodegradable agricultural films. Through the optical performance, mechanical properties, and other research, the results showed that the rare earth complex could convert the sun's ultraviolet light to red light when doped polymer. Moreover, the relative intensity ratio of 5D0/7F2 to 5D0/7F1 of PLA/PBAT/EuTT film could reach 3.79, which implied that the film had strong fluorescence intensity and high color purity. The highest tensile strength of the film could reach 36.7/25.2 MPa, and the elongation at break was 462.8/483.0% in the machine and in the transverse direction when the added amount of Eu (TTA)3(TPPO)2 was 0.1 wt%. The tensile strength of the film was 33.3/20.1 MPa, and the elongation at break could reach 535.8/413.6% when the added amount of Eu (TTA)3(TPPO)2 was increased up to 0.3 wt%. Gel permeation chromatography showed that the Eu (TTA)3(TPPO)2 could cause depolymerization of polylactide, resulting in a decrease in the molecular weight of PLA. Furthermore, the crystallization ability of PLA was also improved. In this paper, the biodegradable films exhibited excellent ultraviolet light conversion ability and mechanical properties.

“…Through precise molecular engineering, AIE-active luminogens (AIE-gens) can be introduced into the polymer structures; the resulting AIE-active samples display the combined advantages of a polymer and AIE-gen, thus expanding the application scope of AIE materials. − AIE-active polymers exhibit the merits of structural diversity, high processability, heat resistance, and excellent mechanical properties compared with AIE small molecules. , However, most AIE-gens usually contain aromatic groups and conjugated subunits as chromophore centers, which results in several disadvantages, such as a complicated structure, expensive synthesis, toxic starting materials, and cytotoxicity. − With the advent of wearable monitoring devices in day-to-day life and brand clothing anticounterfeiting, the development of fluorescent fabrics has seen rapid growth. Over the past decade, fluorescent fibers have been fabricated using various novel techniques, such as melt spinning, electrospinning, and surface coating via a simple physical combination of polymer matrices and luminogens. − However, these fluorescence fibers have displayed poor fluorescence intensity and durability. Besides, the in situ preparation of arbitrary fluorescent patterns by traditional methods still remains a challenge.…”

A new technique is proposed for the in situ printing of fluorescent fabrics with superior fluorescent properties that have the potential for continuous roll-to-roll production in the industry. Nonconjugated chemical moieties were covalently connected to polyethylene/polypropylene nonwoven fabric (PE/PP NWF) to successfully prepare fluorescent PE/PP NWF, which emits a bright blue light and has a high quantum yield (∼83.35%) that can be attributed to a unique aggregation-induced emission effect. The fluorescent PE/PP NWF exhibits excellent fluorescent stability under high shear forces during accelerated laundering and in harsh chemical environments. The fluorescent PE/PP NWF can also be tailored into diverse shapes and printed in situ with high resolution. The versatility of the method was also demonstrated by fabricating fluorescent materials with different polymer matrices such as Nylon 66 fiber and PE terephthalate membrane.

This research concern on producing upholstery fabrics designs inspired from Islamic art which glowing in dark using strontium aluminate Phosphor. Photoluminescent (PL) material such as Phosphor of strontium aluminate (SrAl2O4: Eu2+, Dy3+) is a kind of energy storage material, it can absorb both ultraviolet (UV) and visible lights from the sunlight and keeps emitting light for a period of time in absence of the illumination source at a certain wave length. The research focused on Islamic art as a source of inspiration due to its richness in the floral, geometric, written, abstract and symbolic motifs. So that we use two pure cotton fabrics (100%) with different operational specifications, one of them (plain 1/1) and the other sample (Basket 3/3). These fabrics were used for producing the (PL) upholstery fabrics with seven different concentrations of strontium aluminate Phosphor (SAOED) pigment ranged from (1: 7 wt.%) using a hand printing method to produce fourteen samples. Our findings that there is a direct relationship between air permeability, bending length in weft & warp direction, tensile strength, elongation and the concentrations of (SAOED). The best sample performance evaluated by radar chart for the given properties is sample (A1) with the quality factor percentage (83.4%). According to the quality factor test result the research team decided applied the five innovate designs inspired from islamic art with the same specification of the sample which achieved a high functional property. The statistical analysis of the questionnaire results shows that the best design idea evaluated by radar chart (design two) with the quality factor percentage (86.4%). Therefore, using strontium aluminate Phosphor is considered a technological method that enriches the aesthetics and functional properties of the upholstery fabric design
