Pre-imidization has been found to have a determining role on the final properties of
polyimide (PI) films. In this work, a series of 4, 4′-(hexafluoroisopropylidene) diphthalic …

With the large-scale application and high-speed operation of electronic equipment, the
thermal diffusion problem presents an increasing requirement for effective heat dissipation …

In this study, polyimide fibers at different stages of imidization were characterized by TGA,
DSC, and FTIR. The imidization degree (ID) calculated by TGA was based on the weight …

We report on a series of novel photochromic poly (amide imide) s and their poly (amic acid)
precursors bearing azobenzene chromophores as the side groups. The chemical structures …

We report on how the morphology of the polymer matrix, ie. amorphous vs. semi-crystalline,
affects the gas transport properties in a series of mixed matrix membranes (MMMs) using Cu …

Aromatic polyimide fibers (PI) are usually produced in two steps. The precursor fibers of
polyamic acid (PAA) are fabricated first, and then the fabricated fibers are converted into PI …

This article explores the insights provided by infrared (IR) spectroscopy into the optical
properties and surface morphology of polyethylene (PE) polypropylene (PP), and polyvinyl …

This work is a part of collaborative project between Multidisciplinary University Research
Initiative (MURI) through which an advanced polymeric capacitor films for military …

The paper describes the synthesis and characterization of “T-type” polyimides and their
precursors–poly (amic acid) s. Investigated polymers contained azobenzene derivatives with …

Roll-to-roll nanomanufacturing is the next generation processing technique with advantages
of high throughput and low cost, beneficial for manufacturing functional materials for flexible …
