Polyimides as a polymer class cover an extremely broad property range, from very high-
melting wholly aromatic polyimides to melt-processable polymers. The impetus to their …

High‐performance polymers have been concomitant with advanced technology for half a
century. With the advancement of synthetic chemistry, the recent development of high …

Nanoporous polyhedral oligomeric silsesquioxanes (POSS) containing amine groups
(NH2− POSS) were reacted with poly (amic acid) having anhydride end groups to form …

Monolithic polyimide aerogels (PI-ISOs) have been prepared by drying wet-gels synthesized
via a rather underutilized room-temperature reaction of pyromellitic dianhydride (PMDA) with …

A novel strategy to design molecularly the cavity size and free volume of flexible polyimide
materials via thermal treatment of rigid and cross-linkable polyimides grafted with thermal …

Porous, low dielectric constant polyimide films have been made by a “nanofoam” approach.
The pore sizes generated in the polymer films are in the tens of nanometers range, hence …

The incorporation of small amounts of 3, 5-diaminobenzoic acid (DABA) comonomer
(usually 5–20 mol%) into an ortho-hydroxypolyimide (HPI) precursor constitutes a new …

Two model urethane compounds, dibutyl 4, 4′‐methylenebis (phenyl carbamate)(BMB)
and dioctyl 4, 4′‐methylenebis (phenyl carbamate)(OMO) were prepared by capping 4, 4 …

Thermal decomposition of labile poly (acrylic acid)(PAAc) side chains grafted onto
fluorinated polyimide backbones (see Figure) is used to prepare nanoporous ultra‐low‐κ …

As the demand for next-generation electronics is increasing, organic and polymer-based
semiconductors are in the spotlight as suitable materials owing to their tailorable structures …
