Preparation and Characterization of Low Expansion Transparent Copolyimide Films
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 2,2bis(t...
