Abstract

The invention relates to a high molecule and inorganic nano-particle hybrid film and a preparation method thereof, and particularly relates to a high molecule and inorganic nano-particle hybrid film for doping inorganic particles into a high molecule material by using a sol-gel method and a preparation method thereof. In the high molecule and inorganic nano-particle hybrid film, inorganic nano-particles are uniformly dispersed in the high molecular polymer film and account for 30-50 percent by weight of the total weight of the polymer film. The method comprises the following steps of: (1) preparing an inorganic oxide particular solution; (2) preparing a polymer solution; (3) preparing a high molecule-inorganic nano-particle mixed solution by using a low-temperature sol-gel method; and (4) injecting and drying the mixed solution to form a film. Compared with the prior art, the preparation method provided by the invention is easy and practical, can be used for conveniently and accurately controlling the thickness and the uniformity of the high molecular film, and is easy for production in scale. The inorganic nano-particle doped high molecular film can be widely applied to automobiles, construction and building materials and other fields.

technical field [0001] The invention belongs to the field of polymer film making, and relates to a polymer and inorganic nanoparticle hybrid film and a preparation method thereof, in particular to a polymer and inorganic nanoparticle doped polymer material with a sol-gel method. Nanoparticle hybrid film and method for preparing same. Background technique [0002] 1) Automotive laminated glass [0003] With the continuous improvement of automobile production and people's living standards, public transportation has increasingly become the focus of public attention around the world, and public transportation accidents have become increasingly serious public safety issues. Since the first recorded car accident in 1899, 30 million people have died in car accidents worldwide, more than the death toll from World War II. Statistics show that the driver's human factors cause the highest rate of road traffic accidents. Both the number of accidents and the number of casualties are a...
