The application of fluorinated polyimides in the field of gas separation membranes is
becoming increasingly widespread due to their strong thermal and chemical stability …

Polyimide (PI) films are well recognized for their outstanding chemical resistance, radiation
resistance, thermal properties, and mechanical strength, rendering them highly valuable in …

On account of the urgent demand for wearable devices and flexible displays, high
transparency and heat-resistance of colorless polyimide (CPI) are required for its …

In recent decades, the need to capture carbon dioxide from industrial gas streams, its
storage, and utilization has been justified as a rule by environmental problems. However …

In this work, a binaphthyl-ether tetramine (BNTA) monomer was designed, synthesized, and
reacted with 6FDA to form an in-situ crosslinked polyimide (6FDA-BNTA). Then, novel mixed …

A new homopolymer, 6FDA-CARDO (t-Bu), was prepared from 6FDA-CARDO through one-
step chemical modification by adding bulky tert-butyl groups, using Friedel–Crafts alkylation …

A series of new diamine monomers, with systematic variations in their chemical structure, by
introducing various substituents onto the polymer backbone, have been made to react with …

In this work, a series of symmetrical “H-shaped” tetramine monomers bearing different
amounts of side groups and linking units were designed and synthesized via a simple one …

A series of random 6FDA-MFPAP/BAMF co-polyimides with different MFPAP: BAMF molar
ratios (2: 1, 1: 1, 1: 2, and 1: 3) were synthesized from a novel diamine, 4-(3-methoxy-4 …

Gas membrane separation has become one of the technologies to solve major problems in
energy, environment and other fields. As the foundation and core of membrane separation …
