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%.
