Significance
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.
