Tailoring the performance of polymer composites via altering the properties of the intrapore polymers of MCM-48 nanocomposites as fillers

Nanocomposites based on vinyl-functionalized MCM-48 and polystyrene (PS) or poly(vinyl acetate) (PVAc) have been prepared and used as additives in PS or PVAc matrices. The mechanical performance of the resulting composites indicates that the properties of the intrapore polymers significantly modify the flexibility or rigidity of the materials. The composites become harder and stronger when filled with the MCM-48-PS nanocomposite, in which the intrapore polymer is rigid. Addition of the MCM-48-PVAc nanocomposite, in which the intrapore polymer is more flexible, enhances the flexibility and toughness of the final composite.
