“…Luo et al [8] investigated a PPS nonwoven-based composite separator and the authors concluded that PPS nonwoven-based composite possessed higher porosity and air permeability as well as other improved electrical properties when compared with commercialized polyolefin separator. Chitosan modified PPS-based microfiber membrane for effective antibacterial activity and oil-in-water emulsion separation was fabricated by Huang et al [9] and this membrane had a promising long-term separation in terms of oily wastewater treatment.…”

In this study, the main purpose is to systematically evaluate isothermal and non-isothermal crystallization behavior of short glass fiber-reinforced polyphenylene sulfide polymer composites (PPS/GF) by a wide range of commonly applied models and also to preciously discuss the crystallization evolution and dynamic mechanical properties together with the consideration of thermal aging effects. Some interesting progress concerning this study can be concluded as follows: the Avrami model was used to examine the isothermal crystallization behavior of PPS/GF and the Avrami plot results exhibit that the isothermal crystallization contains primary and second crystallization process. In terms of non-isothermal crystallization, the Jeriorny model and Mo model could describe the mechanism of nucleation and crystal growth of PPS/GF material under study. Also, the activation energy of non-isothermal crystallization is calculated (−58.78 kJ/mol) by Kissinger method. Another important aspect is that thermal aging has an obvious effect on crystallization behaviors of PPS under study. The degree of crystallinity increases from 44% (virgin sample) to 56% after 96 h of aging at 200°C. After a long period of oxidation up to 1080 h at 200°C, the crystallinity degree decreases to 36.6% due to thermo-oxidation effect. DMA results imply that thermal aging may lead to more crosslinking reactions and result into more restriction of molecule mobility in PPS composite materials.

“…At these durations, by increasing the pressure of hot‐pressing, water permeation flux reduces due to the reduced membrane porosity as well as average pore radius of the porous interconnected structure 26,33,34 . For the heat‐treatment duration beyond 1.5 hours, due to the sufficient treatment time, the adverse effects of porosity and average pore radius reduction are covered by the favorable interlayer distance reduction 32 . These properties are achieved due to the elimination of oil droplets entrance into the EFM porous structure and the reduction of oil adhesion to the fibers and the corresponding pore narrowing or even blockage.…”

“…Exerting an external pressure reduces the gap between the layers; as a result, the potential for melting and connection formation between the fibers increases. In such a situation, if temperature is high enough and heat‐treatment duration is long enough for softening or even melting of the polymeric fibers, junctions formed and this reduces porosity of the mat as well as average pore radius of the porous fibrous structure 32,39 …”

Dependence of the polyethersulfone electrospun fibrous membrane (EFM) performance on direct and interactive effects of electrospinning parameters and post heat‐treatment conditions were studied using RSM technique. A designed number of 29 EFM samples with different average fiber thickness and average pore radius were prepared. Modified quadratic models were developed based on the experimental results to predict the membrane performance in oil‐in‐water (O/W) emulsion separation. The low error of permeation flux (7.6%) and oil rejection (11.3%) models guaranteed accuracy of the modeling results. The optimum values of the studied parameters resulting in the membrane with promising performance, including polymeric solution flow rate, hot‐pressing duration, temperature, and pressure were 0.8 mL/h, 1.5 hours, 210°C, and 0.14 bar, respectively. The polymeric solution flow rate and hot‐pressing temperature were found as the most effective parameters on water permeation flux and oil rejection, respectively. The maximum predicted permeation flux and oil rejection of this EFM were 708 LMH and 89%, respectively.

View full text Add to dashboard Cite

The three-dimensional molded interconnected device (3D-MID) has received considerable attention because of the growing demand for greater functionality and miniaturization of electronic parts. Polymer based composite are the primary choice to be used as substrate. These materials enable flexibility in production from macro to micro-MID products, high fracture toughness when subjected to mechanical loading, and they are lightweight. This survey proposes a detailed review of different types of 3D-MID modules, also presents the requirement criteria for manufacture a polymer substrate and the main surface modification techniques used to enhance the polymer substrate. The findings presented here allow to fundamentally understand the concept of 3D-MID, which can be used to manufacture a novel polymer composite substrate.
