Abstract
A procedure for the generation of nanoporous polystyrene (PS) from ordered PS-Poly(ethylene oxide) (PEO) block copolymer using aqueous hydrogen iodide was analyzed. PS-PEO is a common diblock copolymer with established morphological behavior, and the HI-mediated cleavage of aliphatic ether linkages. The treatment of an ordered PS-PEO block copolymer was envisioned, with aqueous HI would yield nanoporous PS, akin to the degradation of Polylactide (PLA) from ordered PS-PLA samples or poly(dimethylsiloxane) from ordered PS-PDMS samples. Analysis of the HI-treated sample by small-angle X-ray scattering (SAXS) showed essentially no change in alignment or principal spacing compared to the PS-PEO starting material.
