The hollow silica nanospheres and its antireflection coatings are getting increasing attention for their distinct structural features and high performance, and they are more and more widely used. The hollow silica nanospheres antireflection coatings are especially used in optics, photovoltaics and optothermal widely for their good antireflection, dirt and scratch resistance and weather resistance. The preparation methods of hollow silica nanospheres using PAA as template are sketched, the influence factors of hollow silica nanospheres making process are analyzed from three aspects of catalyst ammomium hydroxide, template PAA and silica precursor TEOS, and the remove principle and methods of template PAA are expounded. The preparative technique of hollow silica nanospheres antireflection coatings is elaborated, the preparative methods of antireflection coatings sol and the coated methods of antireflaction coatings are summarized, and the calcine function to antireflection coatings is analyzed. The drawbacks existing in the preparation of hollow silica nanospheres antireflection coatings and their improving methods are forecasted.
