抜粋

Porous polyimide (PI) nanoparticles with pores in the form of spherical void were fabricated by adding a second polymer (e.g., poly(acrylic acid)) as a template, which acted as the source of porosity, via the reprecipitation method. The morphology of porous particles was mainly affected by the miscibility of poly(amic acid) (PAA, precursor of PI) and the template. And the diameter of pores varied in the range of 30-100 nm simply by changing the content of proper template. It provides a unique approach for dielectric applications with extendibility to the ultra-low dielectric constant regime (k <2.0).
