Abstract: A method for manufacturing a thick polyimide film includes providing a first and second laminated structures. The first and second laminated structures are heated, and the heated first and second laminated structures are wound together to form a third laminated structure. The first polyamic acid gel film of the heated first laminated structure and the second polyamic acid gel film of the heated second laminated structure are overlapped and bonded together to form a third polyamic acid gel film. Two third laminated structures are wound together to form a fourth polyamic acid gel film. A dehydration ring-closure imidization reaction is applied to the fourth polyamic acid gel film by heating to obtain the thick polyimide film. A thick polyimide film manufactured by the method is also disclosed.
