Research progress in modification of polypropylene with nucleating agent
摘要
Abstract
Polypropylene(PP)produced through current industrial processes has typical drawbacks such as poor thermal properties,electrical properties,and optical properties,especially under extreme conditions like low temperatures or high strain rates.These issues can often be addressed by adding nucleating agents.Nucleating agents can induce hetero-geneous nucleation in PP,leading to a further refinement of the crystalline structure.In this case,there is an increase in the crystallinity of PP and a reduction in the diameter of spherulites,thus improving the various properties of PP.Start-ing from the types of nucleating agents for PP,this paper introduced different categories of alpha-crystalline nucleating agents(inorganic and organic types)and beta-crystalline nucleating agents(inorganic,polycyclic aromatic hydrocar-bons,rare earth compounds,etc.)as well as their respective characteristics.Based on this foundation,the paper also re-viewed the recent development in the nucleating agents for PP and summarized their nucleating effects on the perfor-mance modification of PP.Finally,an outlook was provided for the research direction of nucleating agents of PP in com-bination with their practical applications.关键词
