Porous Polyimide Membranes Prepared by Wet Phase Inversion for Use in Low Dielectric Applications

Porous Polyimide Membranes Prepared by Wet Phase Inversion for Use in Low Dielectric Applications

A wet phase inversion process of polyamic acid (PAA) allowed fabrication of a porous membrane of polyimide (PI) with the combination of a low dielectric constant (1.7) and reasonable mechanical properties (Tensile strain: 8.04%, toughness: 3.4 MJ/m3, tensile stress: 39.17 MPa, and young modulus: 1.1...
