Crosslinked porous polyimides: structure, properties and applications

Chitin and Chitosan: Structure, Properties and Applications

Chitin and chitosan are the most abundant natural amino polysaccharide that are non-toxic, biodegradable and biocompatible. They have become of great interest not only as an underutilized resource, but also as a new functional material of high potential in various fields. They are biopolymers having immense structural possibilities for chemical and mechanical modifications to generate novel pro...

Properties of Fluorinated Polyimides

This paper reports on two fluorinated polyimides synthesized using a fluorinated diamine, 2,2'-bis(trifluoromethyl) -4,4'-diaminobiphenyl (TFDB). One polyimide, synthesized with TFDB and 2,2'-bis(3,4dicarboxyphenyl)hexafluoropropane (6FDA), has a low dielectric constant, high optical transparency, and a low refractive index. The other, synthesized with TFDB and pyromellitic dianhydride (PMDA), ...

Synthesis of cost-effective porous polyimides and their gas storage properties.

Porous polyimide (PI) networks with surface area up to 660 m(2) g(-1) were synthesized by planar structure monomers without detrimental catalysts.
