  • Manufacturing method and foaming manufacturing method of polymethl methacrylate/silica composite material
    Publication number: 20100010109
    Abstract: A manufacturing method and a foaming manufacturing method of polymethyl methacrylate/silica composite material are disclosed. At first, synthesize silica by a sol-gel process. Then, prepare polymethyl methacrylate/silica composite material by bulk polymerization. At last, prepare polymethyl methacrylate/silica foam nanocomposite material from polymethyl methacrylate/silica composite material by a foaming method.
