Abstract
Aerogel is a multifunctional new material.The silica-based aerogel as the most widely studied aerogel material,first industrialized in China in 2004,has been widely used in electronics,construction,thermal insulation,aerospace,energy and other fields.However,compared with foreign countries,there are fewer high-end products in China and the original innovation is slightly insufficient.In this paper,the patents related to silica-based aerogel materials and its preparation technology in the past 20 years were studied and the research hotspots in the past 20 years from the perspective of patents were explored.This paper analyzed the current market competition pattern from the dimensions of market flow and key applicants,and pointed out that the developed countries represented by the United States,Germany and Japan were in the leading position through the global patent layout to achieve a greater control of the market to a certain extent.It focused on analyzing the research hotspots of silica-based aerogel and its preparation technology from the perspectives of technical hotspots and technical routes.At present,aerogel particles,precursor improvement and fiber reinforcement were the research focuses in this field in recent years,and all countries had paid more attention to metal oxide composites and transparent energy storage materials.Then,by sorting out the technical characteristics of Chinese transferred and transformed patents,it helped enterprises to accurately find cooperation partners when seeking technical cooperation.Finally,the research directions that Chinese enterprises needed to focus on in technological innovation were summarized to provide guidelines for future technological research and development.关键词
