Abstract
Quantitative etching of the polydimethylsiloxane block in a series of
polystyrene-polydimethylsiloxane (PS-PDMS) block copolymers is
reported. Reacting the block copolymer with anhydrous hydrogen fluoride
(HF) renders a nanoporous material with the remaining PS maintaining the
original morphology in the bulk. The method is very accurate for
analytical determination of the PDMS content in the samples. Several
morphologies (BCC, HEX and Gyroid) are conserved in the resulting glassy
PS-matrix, as ascertained by small angle X-ray scattering. Especially,
films of mm thickness containing secluded spherical nm wide holes of BCC
symmetry are produced by this procedure.
