제목 Synthesis of microporous polyurea networks by cross-linking copolymerization of tetrakis(4-aminophenyl)methane, tetrakis(4-aminophenyl)silane and 2,2’,7,7’-tetraamino-9,9’-spirobifluorene with diisocyanate
초록 Microporous polyurea networks were synthesized by cross-linking copolymerization of tetrakis(4-aminophenyl)methane, tetrakis(4-aminophenyl)silane and 2,2’,7,7’-tetraamino-9,9’-spirobifluorene with 1,6-diisocyanatohexane. We were able to obtain colloidal dispersions (sols) at concentrations below critical gelation point. The microporous characteristics of the networks were studied with varying the comonomer compositions. The nanopaticles obtained from the organic sol state were characterized using dynamic light scattering, atomic force microscope, and scanning electron microscope. This work was supported by a Korea Science and Engineering Foundation (KOSEF) grant. [2010-0026421]
