A kind of large-area ultra-high molecular weight polyethylene ultra-thin film and preparation method thereof |
| abstract |
The invention relates to a large-area ultra-thin ultra-high molecular weight polyethylene film and a preparation method thereof, belonging to the field of polymer processing. The invention provides a preparation method of a large-area ultra-high molecular weight polyethylene ultra-thin film. The preparation method comprises the following steps: 1) stirring and melting poly ultra-high molecular weight polyethylene, a solvent and an antioxidant to form a uniform suspension 2) The suspension is extruded or banburyed, and then pressed into a gel film; 3) The obtained gel film is stretched, annealed, extracted and dried to obtain a large-area ultra-high molecular weight polyethylene film. The invention provides a preparation method for preparing a large-area ultra-thin ultra-high molecular weight polyethylene film, which can obtain a large-area ultra-thin ultra-thin ultra-high molecular weight polyethylene film with a thickness of 70-200 nanometers and an area of ≥ 0.6 square meters, and the obtained film Has high strength and stability. |
