Abstract

Porous polyimide (PI) nanoparticles have been successfully prepared by the incorporation of a second polymer as the template into poly(amic acid) (PAA, precursor of PI) via the reprecipitation method. First, porous PAA nanoparticles were generated by the injection of mixed PAA-template solution into cyclohexane. Then PAA was converted to PI by two-step imidization without morphology transformation. The morphology of porous PI nanoparticles, which had superficial pores in the range of 30-100 nm, was affected by the miscibility of PAA and template. The formation mechanism was also discussed.
