聚双环戊二烯耐腐蚀性能研究

Study on Corrosion Resistance of Polydicyclopentadiene

为了拓展聚双环戊二烯(PDCPD)材料的应用潜力,利用溶剂浸泡法研究PDCPD材料的耐腐蚀性能。结果表明:PDCPD材料能够耐受大多数极性有机溶剂、酸碱溶液的腐蚀,但在部分强氧化性的浓酸中,PDCPD分子结构的不饱和C C双键易被氧化,导致材料被腐蚀;由于相似相溶原理,在部分非极性和弱极性有机溶剂中,PDCPD材料会发生溶胀腐蚀,造成材料性能下降。

In order to expand the application potential of polydicyclopentadiene(PDCPD)materials,the corrosion resistance of PDCPD materials was studied by solvent immersion method.The results show that PDCPD can resist the corrosion of most polar organic solvents and acid-base solutions,but in some strong oxidizing acids,the unsaturated C C double bond of PDCPD molecular structure is easy to be oxidized,resulting in the corrosion of the material.Due to solubility parameter close principle,the swelling corrosion of PDCPD materials will occur in some non-polar and weak polar organic solvents,resulting in the decline of material properties.
