Polyimide film having low dielectric constant and low hygroscopicity, and manufacturing method therefor |
| abstract |
The present invention relates to a method for manufacturing a polyimide film, and provides a method for manufacturing a polyimide film, the method comprising the steps of: (a) polymerizing an aromatic dianhydride monomer and an aromatic diamine monomer in a first organic solvent to prepare a first polyamic acid; (b) polymerizing a dianhydride monomer and a diamine monomer in a second organic solvent to prepare a second polyamic acid, wherein at least one of the dianhydride monomer and the diamine monomer is an aliphatic dianhydride monomer or an aliphatic diamine monomer; (c) copolymerizing the first polyamic acid and the second polyamic acid in a third organic solvent to prepare a third polyamic acid; (d) preparing a precursor composition containing the third polyamic acid; and (e) forming a film of the precursor composition on a support, followed by imidization. |
