摘要:
针对含氟聚酰亚胺薄膜透明度高但热膨胀系数大的问题,以4,4′-(六氟异丙烯)二酞酸酐(6FDA)为含氟二酐,4,4′-二氨基-2,2′-双三氟甲基联苯(TFMB)为原料,采用引入分子结构相对对称的刚性单体1,2,4,5-均苯四甲酸二酐(PMDA)进行共聚的方法合成了三种含氟比例不同的透明聚酰亚胺薄膜,编号为PI-1、PI-2、PI-3,作为对照,以PMDA和ODA(4,4-二氨基二苯醚)合成了PI-4,并对其性能进行了表征。热重分析表明,引入刚性单体共聚提高了含氟薄膜的热稳定性;介电测试显示,含氟薄膜的介电常数小于传统聚酰亚胺薄膜,PI-1的介电常数小于共聚薄膜PI-2和PI-3;紫外-可见光谱图表明含氟聚酰亚胺薄膜的透光率明显大于传统薄膜,PI-1、PI-2、PI-3的截断波长分别为355nm、360nm和372nm,黄色指数分别为6.4、6.9和8.94,三种薄膜在波长500nm处的透过率均超过90%;拉伸试验显示含氟聚酰亚胺薄膜的拉伸强度远低于传统聚酰亚胺,在添加部分刚性单体后,其力学强度有所增大;四种薄膜的热膨胀系数分别为14.8×10-5/℃、9.9×10-5/℃、5,4×10-5/℃和4,0×10-5/℃,随着PMDA含量的增加,薄膜的热膨胀系数明显降低。
Abstract:
 To overcom the shortcoming of fluorinated polyimide films such as low reaction activity and high coefficien of thermal expansiont, rigid monomer pyromellitic dianhydride(PMDA) were used to copolymerize with two Fluorinated monomers 4,4(hexafluoroisopropylidene)diphthalic anhydride(6FDA) and 2,2bis(trifluoromethyl) benzidine(TFMB) to form a serials of PAA solution, as control, PI-4 were synthesized by PMDA and ODA (4,4 two amino two phenyl ether). After that, the obtained PAA solution was heated at the following order to produce transparent polyimide films, 80℃/1h, 110℃/2h, 150℃/2h, 200℃/1h, 250℃/30min, 300℃/30min, the obtained PI films which had pyromellitic dianhydride content of 0%, 20% and 40% were numbered as PI-1,PI-2,PI-3, relatively, and its phsical and chemical properties were characterized. The thermogravimetric analysis showed that thermal stability of fluorinated films is slightly lower than that of traditional film; the dielectric tests showed that the fluoride film’s dielectric constants were smaller than traditional polyimide film, the dielectric constant of PI-1 is less than PI-2 and PI-3 copolymer films; the UVVis spectra showed that the transmittance of fluorinated polyimide film was significantly higher than that of conventional film, cutoff wavelength and yellow index of PI-1, PI-2, PI-3 was 355 nm, 360 nm, 372 nm, and 6.4, 6.9 , 8.94, relatively.All three films’ transmittance at the wavelength of 500nm were more than 90%; the tensile test showed that the tensile strength of fluorinated polyimide films was much lower than that of the conventional polyimide, but it increased after the addition of rigid monomers; the thermal expansion coefficients of four kinds of films were 14.8×10-5 /℃, 9.9×10-5 /℃, 5.4×10-5 /℃and 4.0×10-5/℃,respectively, which were decreased with the increase of the content of of PMDA content.
