Description

technical field [0001] The invention relates to a nanometer material, in particular to a nanometer material with anti-fog and self-cleaning effects. Background technique [0002] At present, nanomaterials have become the focus of attention as an important frontier field. In our daily life, automobile glass, building glass, decorative glass, etc. require us to maintain and clean frequently, which will cause a large waste of resources, such as water, electricity, labor, etc., in the cleaning of high-rise buildings There are also greater security risks. At the same time, in rainy and snowy weather, the glass of the car is easy to generate fog, which affects the driver's sight, which is an important factor for the frequent occurrence of vehicle accidents. Therefore, the preparation of anti-fog and self-cleaning nanomaterials is very important for the sustainable development of my country's economy. With the increasing demand for anti-fog and self-cleaning nanomaterials, some ...
