摘要: Crosslinked polysulfone/polyhedral oligomeric silsesquioxane (POSS) hybrid networks were synthesized in this work by photoinduced copolymerization of polysulfone dimethacrylate (PSU-DMA) and multifunctional POSS-methacrylamide (POSS-MAAm) with various feed ratios. The morphology the nanocomposites was investigated transmission electron microscopy (TEM), which suggests random dispersion POSS PSU matrix without macroscopic agglomeration. Thermogravimetric analysis results confirmed that thermal stability char yield PSU-DMA/POSS-MAAm increased increase loading. Enhanced glass transition temperatures storage modulus observed to be higher than its precursor polymer.
