Document Type and Number:
Japanese Patent JP6481599
Kind Code:
B2
Abstract:
An inorganic particle-polysiloxane composite comprising inorganic particles having a polysiloxane containing SiR 2 R 3 O 2/2 and SiR 4 R 5 R 6 O 1/2 units grafted to their surface is prepared without mechanical treatment. The inorganic particles have an average particle size of 1-200 nm, the polysiloxane may be bonded to the inorganic particle surface via a siloxane coating layer containing SiR 1 O 3/2 units, and a total of siloxane constituents is 20-20,000 pbw per 100 pbw of the inorganic particles. R 1 to R 5 are H, alkyl, alkenyl, aryl or dimethylsiloxy group, and R 6 is H, alkyl, alkenyl, aryl, dimethylsiloxy, alkoxy or hydroxyl group. The inorganic particle-polysiloxane composite is dispersible in silicone oil, and so a transparent functional silicone material is obtained.
