AbstractThis paper summarizes and reviews the research on electromagnetic
interference (EMI) shielding with intrinsically conducting polymers (ICPs),
mainly polyaniline (PANI) and polypyrrole (PPY), and their composites in various
frequency ranges. ICPs are new alternative candidates for EMI shielding
applications due to their lightweight, corrosion resistance, ease of processing,
and tunable cond... hiện toàn bộ
AbstractThis overview article discusses fundamental principles of gas sorption
and transport in rubbery and glassy polymers and material selection guidelines
for gas separation membranes. Comparisons between the performance of
membrane‐based gas separation systems and more conventional technologies in key
commercial applications are provided. Companion articles in this special edition
focus on sta... hiện toàn bộ

AbstractInterpenetrating polymer networks (IPNs) have been the subject of
extensive study since their advent in the 1960s. Hydrogel IPN systems have
garnered significant attention in the last two decades due to their usefulness
in biomedical applications. Of particular interest are the mechanical
enhancements observed in “double network” IPN systems which exhibit nonlinear
increases in fracture pr... hiện toàn bộ
AbstractAcrylamide (AAm)‐2‐acrylamide‐2‐methylpropanesulfonic acid sodium salt
(AMPSNa) hydrogel and AAm‐AMPSNa/clay hydrogel nanocomposite having 10 w% clay
was prepared by in situ copolymerization in aqueous solution in the presence of
a crosslinking agent (N,N′‐methylenebisacrylamide (NMBA)). Swelling properties
and kinetics of the hydrogel samples were investigated in water and aqueous
solutio... hiện toàn bộ
AbstractA new cost‐effective approach to enhance gel strength of superabsorbent
hydrogels was invented. Superabsorbent hydrogel composites (SHCs) were prepared
through an optimized rapid solution polymerization of concentrated partially
neutralized acrylic acid in the presence of a crosslinking agent under normal
atmospheric conditions. Kaolin was used as an inorganic component in the
polymerizati... hiện toàn bộ
AbstractIonic liquid monomer couples were prepared by the neutralization of
1‐vinylimidazole with vinylsulfonic acid or 3‐sulfopropyl acrylate. These ionic
liquid monomer couples were viscous liquid at room temperature and showed low
glass transition temperature (Tg) at −83 °C and −73 °C, respectively. These
monomer couples were copolymerized to prepare ion conductive polymer matrix.
Thus prepared... hiện toàn bộ
Ever since the discovery of polymer composites, its potential has been
anticipated for numerous applications in various fields such as
microelectronics, automobiles, and industrial applications. In this paper, we
review filler reinforced polymer composites for its enormous potential in
microelectronic applications. The interface and compatibility between matrix and
filler have a significant role i... hiện toàn bộ
AbstractThe crystallization kinetics and degree of crystallinity of
polycaprolactone (PCL) were studied using the technique of differential scanning
calorimetry (DSC). The crystallization exotherms measured using DSC were
analyzed using a modified Avrami equation. The modification limited the analysis
of the data to the primary crystallization process, where the Avrami equation is
applicable. Both... hiện toàn bộ
AbstractUsing diethylene glycol (DegOH) as non‐solvent additive (NSA) and N,
N‐dimethylacetamide (DMAc) as solvent (S), polyethersulfone (PES) flat sheet
membranes were prepared via immersion precipitation combined with the vapor
induced phase separation (VIPS) process. Light transmittance was used to follow
the precipitation rate during the immersion process as well as during the VIPS
stage. As t... hiện toàn bộ
