摘要：
An ordered nanoporous monolith was prepared from a poly(isoprene-b-dimethylsiloxane) (PI-PDMS) hexagonally packed cylinder precursors. The PDMS cylinders were macroscopically aligned, the PI was crosslinked with dicumyl peroxide, and the PDMS was removed using tetrabutylammonium fluoride. The stability of the pores depended on the modulars of the matrix. At high crosslink density the pores were stable, but they collapsed at a low crosslink density. The nanoporous materials could be swollen in toluene.
