Wholly aromatic polyamides (aramids) are considered to be high-performance organic
materials due to their outstanding thermal and mechanical resistance. Their properties arise …

High‐performance polymers based on amide aromatic rings are known as wholly aromatic
polyamides or aramids. The arrangement and admirable properties of aramids are built on …

Poly (ethylene oxide)(PEO)-containing polymer membranes are attractive for CO2-related
gas separations due to their high selectivity toward CO2. However, the development of PEO …

Composite nanofiltration membranes comprising polyamide active layer and
polyacrylonitrile (PAN) support were prepared by 1-ethyl-(3-3-dimethylaminopropyl) …

In this study a range of commercial polyamide membranes intended for reverse osmosis
service are compared. Significant differences in membrane chemistry are detected through …

A new aromatic diacid monomer viz., 4-(4′-carboxyphenoxy)-2-pentadecylbenzoic acid
was synthesized starting from cardanol and was characterized by FTIR, 1H-and 13C NMR …

Poly (phenylene sulfide benzimidazole) has been synthesized and tested as a potential
material for high-temperature proton transport. A high content of sulfide bonds has been …

In consideration of the rigid structure of meta-aramid (PMIA) and its difficulty in processing
and dyeing, this work describes the preparation of two intrinsically chromogenic, high …

Driven by sustainable development and low-carbon policies, many high-performance bio-
based polyesters are produced. Our previous work uncovered the high barrier but low …

In recent years, polyimide (PI) hybrid materials have received considerable attention owing
to the dramatic enhancements over their pristine state in thermal stabilities, mechanical …
