n the past few years, the application of nano-titanium
dioxide (nano-TiO2) on catalysis and ultraviolet (UV)
shielding has attracted much attention. At the same time,
the usage of nano-TiO2 as a UV absorber is limited in many
practical areas because of the photocatalytic activity. In
order to utilize nano-TiO2 as UV absorbers in a safe and
effective manner, the silica coated nano-titanium dioxide
(nano-TiO2@SiO2) was prepared by sol-gel process. The
nano-TiO2@SiO2 was added into reactive bisphenol-A
polycarbonate/diallyl phthalate (BAPC/DAP) blends and
its effect on the reaction-induced phase separation and
properties of the composites were investigated. The
results showed that the nano-TiO2@SiO2 could affect the
phase morphology of the BAPC/DAP/nano-TiO2@SiO2
composites by lowering the phase separation rate. The
higher the content of nano-TiO2@SiO2, the more difficult
of the phase separation proceeding in the composites,
which would lead to a rougher fractured surface of the
composite film, much higher UV absorption ability and the
transmittance of visible light. Meanwhile, the composites
with proper content nano-TiO2@SiO2 had highest glass
transition temperature, i.e., 0.5 wt% compared with 0.1
wt% and 1 wt%.
