| titleOfInvention | High Strength Polyimide nanofiber biaxial stretching film and its preparation method and application |
| abstract | The invention provides a kind of polyimide nano-fiber biaxial stretching film, it is by electrospinning polyamic acid nano-fiber for production of non-woven longitudinally 1-10 times, warp, horizontal 1-4 times of polyimide nano-fiber biaxial stretching film that both direction stretching imidization forms under the high temperature of 200 to 400 DEG C; Described polyimide structures is as shown in the formula shown in (I), wherein, and R 1 The dianhydride residue containing aromatic ring, R 2 Be the diamines residue containing aromatic ring, n is polymer repeat unit number, between 100 to 500. That High Strength Polyimide nanofiber biaxial stretching film provided by the invention has is high temperature resistant, high chemical stability, excellent mechanical strength, good gas permeability and poisture-penetrability. The present invention also provides the preparation method of described polyimide nano-fiber biaxial stretching film, and as the application of liner and fabric and the aerospace light sail material etc. of the reinforcer in electrical insulation film, high temperature filtration, lithium battery diaphragm, resin composite materials, rainproof breathable garment. |
