    摘要: A phenolic resin that increases its toughness by polydimethylsiloxane and a process of preparing the same is provided. Polydimethylsiloxane is added as a coupling agent in a γ-glycidoxypropyltrimethoxysilane-modified phenolic resin to improve the compatibility between polydimethylsiloxane and the phenolic resin. Then, tetraethoxysilane is added to conduct hydrolysis condensation and obtain tougher and thermally stable phenolic resin.

    摘要: A thermo-interface material composite uses a thermo-interface material containing silver nanowires. The silver nanowires have high aspect ratios, high thermo-conductivity coefficients and good anti-oxidation capabilities. Hence, an amount of silver nanowires can be added fewer than that of a traditional metal or ceramic powder. In this way, defects on device surface can be speckled during a dispersal process for improving adhesion between devices. Thus, a thermo-interface material is fabricated to obtain a high thermo-conductivity coefficient for further forming a thermo-channel.
