Abstract

Barium titanate@ poly (methyl methacrylate) (BT@PMMA) nanocomposites were prepared via in situ atom transfer radical polymerization (ATRP). It was observed that the BT nanoparticles were coated with PMMA and excellently dispersed in the polymer matrix. Compared with the BT/PMMA nanocomposites prepared by the traditional solution blending, BT@PMMA nanocomposites show higher thermal conductivity and lower dielectric loss. The result is attributed to the strong interfacial bonding between the BT nanoparticles and the PMMA matrix.
