摘要：

CNTs@SiO2 core-shell nanoparticles were synthesized via tetraethyl orthosilicate (TEOS) hydrolyzing and condensing on the CNTs' surface. The effect of reaction parameters, including temperature, time, ratio of the cationic surfactant cetyltrimethyl ammonium bromide (CTAB)/CNTs, and TEOS/CNTs on the structure of nanoparticles was investigated. Results showed that the optimized temperature, time, ratio of CTAB/CNTs were 30 degrees C, 24 hours, and 1: 2, respectively. The controlled thickness of SiO2 shell, ranging from 0 to 35 nm, can be obtained by controlling the ratio of TEOS/CNTs in the range of 0.1 mL/ to 1.0 mL / 0.1 g. The CNTs@SiO2 nanoparticles are promising candidate as the fillers for electronic packaging application.
