A series of HFBAPP/6FDA/BPADA fluorinated phenyl ether-containing polyimide films were prepared using 2,2-bis [4-(4-aminophenoxy)phenyl] hexafluoropropane (HFBAPP) as the diamine monomer, 2,2′-bis (3,4-dicarboxylic acid) hexafluoropropane dianhydride (6FDA) and bisphenol A-type diether dianhydride (BPADA) as the dianhydride monomer. The effects of ether bond and trifluoromethyl on the comprehensive performance of polyimide films were analyzed and compared by changing the ratio of dianhydride monomer. The results show that with the increase of trifluoromethyl content and the decrease of ether bond content, the optical and thermal properties of the HFBAPP/6FDA/BPADA fluorophenyl ether-containing polyimide films increase, while the mechanical properties decrease, the glass transition temperature can reach 247.3℃, the residual carbon rate at 800℃ can reach 56.3%, the maximum transmittance in the visible range is 88.2%, and the maximum tensile strength is 84.7 MPa.
