Nano-SiO2 hybrid particles segment with grafted 2-phenoxy ethyl acrylate(PHEA) and polystyrene(PS) were sysnthesised using step by step atom transfer radical polymerization(ATRP) method. PHEA had active hydroxyl group of rich, and it could combine with carbon fiber to form a chemical bond, PHEA and PS could form a good entanglement and diffusion and matrix of different properties of the matrix, to realize adaptive fiber with different properties to construct the strong interaction, to improve the interfacial bond strength. The nano-SiO2 hybrid particles was characterized by the element analysis, Fourier transform infrared spectroscopy, dynamic mechanical thermal analysis, thermogravimetric analysis and other means which ensured that the molecular structure of the target product could match with molecular structure of the design.
