A fiber includes polyester copolymerized with diacid monomer, esterified diacid monomer or combination thereof with a polyol monomer. The diacid monomer, esterified diacid monomer or combination thereof includes (1) furan dicarboxylic acid, dialkyl furandicarboxylate, or combination thereof or (2) furan dicarboxylic acid, dialkyl furandicarboxylate, or combination thereof and spiro-diacid. The polyol monomer includes (3) C-Cpolyol or (4) C-Cpolyol and spiro-diol. The diacid monomer, esterified diacid monomer or combination thereof and the polyol monomer meet: (a) diacid monomer, esterified diacid monomer or combination thereof includes (2) furan dicarboxylic acid, dialkyl furandicarboxylate, or combination thereof and spiro-diacid, (b) polyol monomer includes (4) C-Cpolyol and spiro-diol, or (c) a combination thereof. The polyester has a viscosity at 30&#xb0; C. of 0.5 dL/g to 1.5 dL/g, and an amount of spiro-diol or spriro-diacid is 500 ppm to 2000 ppm based on a weight of the furan dicarboxylic acid, dialkyl furandicarboxylate, or the combination thereof.

Fiber and method of manufacturing the same

Disclosed is a method of transferring a carbon conductive film, including: providing a first substrate, and forming an inorganic oxide layer on a surface of the first substrate, wherein the inorganic oxide layer has a total surface energy of 30 mJ/mto 75 mJ/m, and a dispersive surface energy to the total surface energy ratio of 0.4 to 0.8. A carbon dispersion is coated on the inorganic oxide layer, and then dried to form a carbon conductive film on the inorganic oxide layer. The carbon conductive film is dipped into a solvent to separate the carbon conductive film and the inorganic oxide layer. The separated carbon conductive film is attached to a second substrate, thereby transferring the carbon conductive film onto the second substrate.
