Poly(3-hexylthiophene) macroinitiators were synthesized by chain-growth polycondensation using Ni-catalyst, followed by hydrolysis and esterification. Poly(3-hexylthiophene)-b-Poly(3-(trimethoxysilyl)propyl methacrylate)s (P3HT-b-PTMSPMA) diblock copolymers with low polydispersities were obtained via atom transfer radical polymerization (ATRP) of TMSPMA from the P3HT macroinitiator. Silica substrates were coated with P3HT-b-PTMSPMA diblock copolymer by the immersion or dip coating method. We studied their morphology using atomic force microscopy, and their chemical composition using X-ray photoelectrospectroscopy. |
