ODA/ODPA/6FDA共聚型FPI薄膜的制备及性能
|
摘要
以4,4’-二氨基二苯醚(ODA)为二胺单体,2,2’-双(3,4-二羧酸)六氟丙烷二酐(6FDA)和4,4’-联苯醚二酐(ODPA)为二酐单体制备出一系列不同二酐单体比例的共聚型含氟聚酰亚胺(FPI)薄膜并对其性能进行研究。结果表明:随着单体6FDA摩尔比例的增加,薄膜的力学性能有所降低,而介电性能、光学性能和疏水性明显提高,所得FPI薄膜介电常数最低可达1.90,透过率最高为88.94%,吸水率仅为0.97%,拉伸强度超过40.31MPa。
By using 4,4'-diaminodiphenyl ether as diamine monomer,2,2'-Bis(3,4-anhydrodicarboxyphenyl)hexafluoropropane and 4,4'-oxydiphthalic anhydride as dianhydride monomers,a series of fluorinated copolyimide(FPI)films was prepared and their properties were studied.The results showed that with the increase of the mole ratio of 6 FDA,the mechanical properties of FPI films were reduced,while the electrical properties,optical properties and hydrophobicity were significantly improved.The minimum dielectric constant of FPI was 1.90.The transmittance was up to 88.94%.The water absorption rate was only 0.97%.The tensile strength exceeded 40.31 MPa.
