Abstract

Polymer brushes on cotton fibers have been prepared by combining the self-assembled monolayer of initiators and surface-initiated atom transfer radical polymerization (SI-ATRP). Two initiators were compared: One was 3-(trichlorosilyl)propyl 2-bromo-2-methylpropanoate, and the other was 2-bromoisobutyryl bromide. The poly(methacryloyloxy)ethyl-trimethylammonium chloride (PMETAC) brushes were prepared by ATRP on the cotton surfaces modified by the two initiators. Scanning electron microscopy (SEM) measurement of the polymer brushes imaged similar morphology when they were treated with two different initiators. The trichlorosilyl initiator has higher graft density due to additional cross-linked products of the chlorosilane on cotton surface. The effect of the concentration of initiators was also investigated systematically.
