摘要
聚合物/纳米二氧化硅复合材料的制备方法大体包括共混法、原位聚合法和溶胶-凝胶法,如今纳米二氧化硅在树脂基复合材料的改性、新型塑料添加剂、功能纤维添加剂和橡胶改性等领域具有广泛的应用。本文还基于聚合物/二氧化硅纳米复合材料的专利数据,对中国专利中的专利申请的相关领域的申请时间分布、申请人情况和技术构成等角度进行分析表明国外申请人的专利申请偏重保护产品,而国内申请人的专利申请仅只偏重保护方法。在中国申请的专利中,外国申请人一般企业居多,中国申请人主要是高校和科研院所。
The methods of producing polymer /nano SiO2composite comprise mixing processing、in situ polymerization and sol-gel processing. Now the nano SiO2is widely used for modifying of resin matrix composite,new plastic additives,functional fiber additives and modification of rubber,etc.. The analysis for related field in patent application of China＇s patents,distribution of application time and applicant condition based on data of China＇s patents of polymer /nanoclay composite showed,that the application claims of the foreign applicants were usually product claims,but the application claims of the applicant at home were usually process claims. Among the application in China,the foreign applicants were mainly enterprises in principal and the applicants at home were mainly universities and research institutes.
