Patent ID: 8133931

Claim:
An acrylate nanocomposite material, comprising: a inorganic nano-particle obtained from an inorganic nano-particle colloidal solution and a coupling agent, said inorganic nano-particle colloidal solution comprising a surface that has a first inorganic nano-particle with a first silanol functional group, said coupling agent comprising an acrylate group at one end, and one to three alkoxide group at the other end, wherein said coupling agent undergoes a hydrolysis reaction after which said alkoxide group forms a second silanol functional group, said first and second silanol functional groups then react with each other to form a bonding therebetween, resulting in a reactive acrylate group on the surface of said inorganic nano-particle; an acrylate monomer with at least two acrylate groups; an imidized acrylate oligomer which comprises a first structure and a second structure, said first structure comprising an imide oligomer formed from a diamine monomer and a dianhydride monomer, said second structure is a hydroxy acrylate monomer; and a photo-initiator, wherein said acrylate nanocomposite material has an organic/inorganic 3D network formed through a photopolymerization reaction.
