Abstract

Poly(2,6-diimidazo [4,5-b:4′5′-e]pyridinylene-1,4(2,5-dihydroxy) phenylene) (PIPD) was synthesized via polycondensation in phosphorus acid and separated as nano-spheres about 50 nm in diameter. When a heterogeneous additive, acid-treated carbon nanotubes, or calcium carbonate nanoparticles were present during polycondensation, nano-spheres near or larger than 100 nm could be obtained. The morphology of PIPD nano-spheres was observed using transmission and scanning electron microscopy. The thermal behavior and the relative composition of the nano-spheres were characterized using thermal gravimetric analysis. The function of the additives was explored in terms of heterogeneous nucleation. The effect of the solvents used for sphere separation was also considered.
