A novel CaO·4B2O3·2H2O–SiO2 nanocomposite with good thermal stability has been in situ synthesized, in which the SiO2 nanospheres are supported on the CaO·4B2O3·2H2O nanosheets. As a comparison, single CaO·4B2O3 ·2H2O nanosheet with the thickness of 100 nm, single SiO2 nanosphere with the diameter of about 100 nm, and their physical mixture were also prepared, respectively. On the basis of characterizations of XRD, FT-IR, TGA, SEM and TEM, the fire performance of CaO·4B2O3 ·2H2O–SiO2 nanocomposite to polypropylene was studied. It is demonstrated that the flame retardancy of prepared sample was prominently stronger than those of single CaO·4B2O3 ·2H2O nanosheet and their physical mixture. Furthermore, the mechanical property of polypropylene/CaO·4B2O3·2H2O–SiO2 composite was also assessed. The possible formation mechanism of the nanocomposite and its flame-retardant mechanism were put forward. It has prospect as possible flame retardant to polypropylene and other polymers.

Abstract The application of ceramic materials is limited due to the complicated preparation process and intrinsic brittleness. In this work, a pressureless manufacturing route that enables the formation of barium aluminosilicate (BAS) glass-ceramic consisting of internal β-Sialon fibers with enhanced thermal conductivity is developed. By adjusting the carbon source content, composites with different Sialon contents can be easily fabricated. The thermal conductivity of the sample with 3.5 wt.% is improved to 5.845 W/m ∙ K with the Sialon content of 26 wt.% in the composite, which is 112.64 % higher than that of the pure BAS matrix. The theoretical models suggest that the enhanced thermal conductivity is mainly ascribed to the thermal conduction network constructed by Sialon fibers. This work provides a method with industrial application prosperity to fabricate the high temperature ceramic matrix composite of different sizes and complex shapes.
