摘要： A method of forming a film is provided, which includes providing a sheet from a polyamide composition; and biaxial stretching of the sheet to form a film, wherein the polyamide composition includes a blend of a first polyamide and a second polyamide. The first polyamide has a repeating unit of and the second polyamide has repeating units of The second polyamide is a crystalline random copolymer. The sheet of the polyamide composition is biaxially stretched at a rate of 20 mm/sec to 100 mm/sec.

摘要： A liquid crystal polymer (LCP) composite film is provided. The LCP composite film includes 88 to 99 weight percent of a liquid crystal polymer based on the total weight of the LCP composite film and 1 to 12 weight percent of a toughening agent based on the total weight of the LCP composite film. The toughening agent includes a copolymer selected from a group consisting of a thermoplastic polyolefin elastomer, a glycidyl methacrylate copolymer, a polystyrene elastomer, a polyester elastomer, and a mixture thereof.
