Synthesis of Monodispersed Hollow Silica Nanospheres with Ultrafine
Grain Size for Optical Polymer
Abstract
Hollow silica nanospheres (HSNs) have been widely used as antireflection
coatings. However, it is difficult to incorporate them into optical
polymer matrices because of their larger size and agglomerations
problem, making the haze and transparency worse. Herein, the sub-20 nm
HSNs were firstly synthesized by a reverse microemulsion method and the
scale-up preparation was successfully achieved in a rotating-packed-bed
reactor. The prepared nanocomposites possess super-high transparency and
almost unchanged haze.
