摘要
In this study, a polysilane-modified graphene oxide (GO) and carbon nanotube (CNT) nanocomposite (GO/CNTs-Si) was prepared as a thermal conductive nanofiller to enhance the thermal and mechanical properties of silicone rubber composites. By gamma-ray-radiation 3-methacryloxypropyltrimethoxy silane (MPTMS) was polymerized on the surface of GO and CNTs to improve the interfacial interaction between the GO/CNTs-Si and SR matrix. FTIR characterization results demonstrated that polysilane modified the GO/CNTs successfully. The pristine GO/CNTs and resultant GO/CNTs-Si were individually incorporated into alpha,omega-dihydroxypolydimethylsiloxane to vulcanize SR composites. Compared with SR-GO/CNTs, SR-GO/CNT-Si exhibited better mechanical and thermal performance. Moreover, the time-dependent complex modulus of SR-GO/CNTs-Si was much higher than that of SR-GO/CNTs, which indicates longer service time and more stable performance. In terms of electronic packaging, SR-GO/CNTs exhibited better performance than the 1180B counterpart. The low value of warpage of chip packaged by SR-GO/CNTs implied that SR-GO/CNTs-Si could have potential application as the thermal interface electronic packaging material.
