  • Patent number: 8530613
    Abstract: Disclosed herein is a method for preparation of a meso-porous polymer nano-composite material which includes: drying a solid material having pores under vacuum; adding a first organic solvent to the vacuum dried solid material in the reactor and dispersing the first organic solvent in pores of the solid material; adding a constant amount of a material having radicals or functional groups relative to weight of the mixture containing the solid material and the first organic solvent in a reactor, and agitating the mixture; introducing a polymerization initiator into the reactor; using a second organic solvent to filter and wash the reaction product after completion of the polymerization; and drying the treated product to eliminate the second organic solvent from the same after removal of the unreacted material having radicals or functional groups as well as the polymerization initiator from the product.

  • Publication number: 20110172084
    Abstract: Disclosed herein is a method for preparation of a mesoporous polymer nano-composite material, more particularly, a method for preparation of a meso-porous polymer nano-polymerized composite material which includes: drying a solid material having pores under vacuum at ambient temperature and pressure; adding a first organic solvent to the vacuum dried solid material in the reactor and dispersing the first organic solvent in pores of the solid material by an ultrasonicator to remove air while wetting a surface of the solid material with acetonitrile; adding a constant amount of a material having radicals or functional groups relative to weight of the mixture containing the solid material and the first organic solvent in a reactor, which was prepared in the above step, and agitating the mixture; introducing a polymerization initiator into the reactor containing the mixture prepared in the above step, in order to initiate polymerization of the mixture in the reactor; using a second organic solvent to filter and w
