“…[26][27][28][29][30] Different from these chemical and physical approaches, several 3-dimensional CNTs-micron substrate hybrid constructions with distinguished morphology have been designed and synthesized in recent years, providing a promising route to improve the CNTs dispersion in composites. [31][32][33] In our previous researches, by controlling critical synthesizing parameters, several CNTs-based hybrid constructions with different structures and morphology (diameter, length, density, and arrangement of CNTs array) have been designed and successfully synthesized through chemical vapor deposition (CVD) method, such as CNTs-alumina (Al 2 O 3 ), CNTs-glass fiber (GF), CNTs-porous spherical silica core(SiO 2 ), CNT-graphene nanoplatelets(GNPs), CNT-silicon carbide (SiC), CNTsilica coated reduced graphene oxide (SiO 2 @RGO). [34][35][36][37][38] He et al 35 reported a CNT-Al 2 O 3 hybrid reinforced epoxy composite, where a 56% enhancement in thermal conductivity was obtained in comparison with pure epoxy.…”
