| titleOfInvention | A kind of high tenacity liquid crystal polymer film and preparation method thereof |
| abstract | The invention belongs to the technical field of high molecular polymers, and in particular relates to a high-toughness liquid crystal polymer film and a preparation method thereof. The liquid crystal polymer film of the present invention comprises a liquid crystal polymer, and the liquid crystal polymer is made of the following monomers: p-hydroxybenzoic acid, 6-hydroxyl-2-naphthoic acid, biphenol, tetrafluoroterephthalic acid formic acid. The preparation steps include prepolymerization, solid phase polycondensation, mixing, melt extrusion, drawing, coiling and heat treatment. In the present invention, the toughness of the liquid crystal polymer film can be significantly improved by introducing a novel monomer tetrafluoroterephthalic acid, p-hydroxybenzoic acid, 6-hydroxy-2-naphthoic acid, and biphenyl diphenol, which can be subjected to -60°C There is no cracking phenomenon after the cold and heat cycle at ~200°C, and the service life is further extended, which is better suitable for environments with large temperature differences. |
