Abstract :
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°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.
