Partially-Fluorinated Polyimides using Aliphatic Diamines
Two series of polyimides were created in order to address several of the existing problems with gas permeation membranes used today. These issues include the lack of flexibility and inverse ratio that exists between selectivity and permeation. The approach taken in order to solving the flexibility …

High temperature nanofoams based on ordered polyamide matrices
Polyimides are one class of high temperature materials that have been extensively used in the microelectronics industry in passivation and protection. The extremely good thermal stabilities, along with desirable mechanical and electrical properties, have led to their use in integrated circuits and …

Synthesis and Characterization of Thermosetting Polyimide Oligomers for Microelectronics Packaging
… and experimental (Mn) values. Crosslinked polyimides were obtained by solution or melt processing the oligomers into films and gradually heating in a programmed temperature manner up to the appropriate reaction temperature for the phenylethynyl groups, which is approximately 350-400°C. …

Fabrication and Characterization of Polyimide-based Mixed Matrix Membranes for Gas Separations
… membranes based on zeolites incorporated into fluorinated polyimides were fabricated and characterized in this study. The first system consisted of a polyimide (6FDA-6FpDA-DABA) with carboxylic acid groups incorporated into its backbone and amine-functionalized zeolite particles (ZSM-2). FTIR …
