摘要
针对聚降冰片烯材料的传统热性能提高改性策略会导致光学性能大大下降的问题,文中以全氟己基碘烷、对溴苯胺和纳迪克酸酐等原料设计合成了一种侧基带有对全氟己基苯结构的降冰片烯二甲酰亚胺单体,并将其通过开环易位聚合制备了一种新型含氟降冰片烯基均聚物(PNANPF6),以及合成了侧基分别为苯(PNANP)、对甲基苯(PNAN-PC1)、对三氟甲基苯(PNANPF1)、对己基苯(PNANPC6)4种结构相似的均聚物作为对照,通过核磁共振波谱和红外光谱表征证明了聚合物的成功制备.结果表明,在热性能和力学性能可基本保持的前提下,PNANPF6的水/正十二烷接触角相比PNANP提高了18°/26°;在400 nm/800 nm处的透光率相比PNANP提高了36%/22%.充分证明酰亚胺、苯环和全氟己基结构的引入可协同提高降冰片烯聚合物的光学性能和疏水疏油性能.为新型多功能降冰片烯聚合物的制备提供一条新思路.
Abstract
The optical properties of polynorbornene materials greatly decreased due to traditional modification strategies of improving thermal properties.A kind of norbornene dicarboximide monomer with the structure of p-perfluorohexyl benzene was designed and synthesized by using perfluorohexyl iodide,p-bromoaniline and nadic anhydride.And a novel fluorinated norbornyl homopolymer(PNANPF6)was prepared by ring-opening metathesis polymerization.As contrast groups,four homopolymers with similar structure including benzene(PNANP),p-methylbenzene(PNANPC1),p-trifluoromethyl benzene(PNANPF1)and p-hexylbenzene(PNANPC6)were synthesized.The structures of polymers were demonstrated by NMR and IR spectra.Under the premise that the thermal and mechanical properties can be basically maintained,the water/n-dodecane contact angle of PNANPF6 is 18°/26° higher than that of PNANP.Besides,the transmittance at 400 nm/800 nm is 36%/22%higher than that of PNANP.These results fully prove that the introduction of imide,benzene and perfluorohexyl structures can synergically improve the optical properties,hydrophobicity and oleophobicity of norbornene polymers.This study provided a new strategy for the preparation of novel multifunctional norbornene polymers,as well as laid a theoretical foundation for the expanding application of polynorbornene materials.
