摘要
研究了聚偏氟乙烯(PVDF)膜的专利技术发展态势。利用IncoPat全球专利数据库,从专利申请趋势、专利申请区域、专利申请人、专利申请技术分布和专利技术5个方面进行统计分析,研究了聚偏氟乙烯膜国内外发展情况,有助于国内相关企业对聚偏氟乙烯膜领域的技术发展有较为全面的了解。
The patent technology development trend of polyvinylidene fluoride(PVDF)membranes is studied. Based on the IncoPat global patent database, the statistical analysis is carried out from five aspects: patent application trend, patent application area, patent applicant, patent application technology distribution and patent technology. The development of polyvinylidene fluoride membranes is revealed. It is helpful for domestic enterprises to have a comprehensive understanding of the technical development of polyvinylidene fluoride membranes.
