基于专利的全球纳米材料应用研究

Application Research of Global Nanomaterials Based on Patents

本文利用Innography专利数据库,对2000—2019年全球纳米材料领域的专利产出情况进行研究,从多个维度分析了纳米材料应用领域的发展态势。研究结果显示:自2000年起纳米材料领域快速发展,我国是纳米材料领域最主要的创新国家,其次是美国和韩国。近年来,纳米金属材料领域的发展最为迅猛,是全球关注的焦点,主要集中在电极、半导体器件、催化剂等技术领域。其次是纳米晶体和纳米玻璃材料,主要集中在半导体器件、光学器件、电极、催化剂、表面处理、电化学测试分析等技术领域。我国专利权人在纳米高分子材料应用领域的创新能力较强,在纳米复合材料应用领域的创新能力较弱。

In this paper,Innnography patent database was used to study the global patent output in the field of nanomaterials between 2000-2019,and the development trend of nanomaterials application field was analyzed from multiple dimensions.The research results show that the field of nanomaterials has developed rapidly since 2000,and China is the leading innovative country in the field of nanomaterials,followed by the United States and South Korea.In recent years,the field of nano-metal materials has developed most rapidly,which is the focus of global attention,mainly focusing on the electrodes,semiconductor devices,catalysts and other technical fields,followed by nanocrystals and nanoglass materials,mainly focusing on the semiconductor devices,optical devices,electrodes,catalysts,surface treatment,electrochemical testing and analysis,and other technical fields.The patentees in China possess strong innovation ability in the application field of nanopolymer materials,but weak innovation ability in the application field of nanocomposite materials.
