| titleOfInvention | Preparation method of polysiloxane imide micro-nano porous fiber non-woven fabric |
| abstract | The invention relates to a preparation method of polysiloxane imide micro-nano porous fiber non-woven fabric, which is prepared by taking aromatic diamine, aromatic dianhydride, silicon capping agent, modifier polysiloxane precursor, imidization catalyst, micro-nano pore stabilizer, pigment and solvent as raw materials and adopting an electrostatic spinning device, a graphite caterpillar dynamic mold and a far infrared radiation heating tunnel integrated process, wherein the width of the non-woven fabric is 10-5000 mm, the diameter of the fiber is 100-1000 nm, the diameter of the micro-nano pore in the fiber is 50-800 nm, and the glass transition temperature of the polysiloxane imide micro-nano porous fiber non-woven fabric is 260-350 ℃. The invention uses the solvent in the imidization process and micromolecule volatile produced in the polycondensation reaction as a micro-nano porous forming mechanism; polysiloxane precursors and silicon end capping agents are introduced into polyimide, so that the mutual dispersion and reaction degree of the components are improved; the formation of micro-nano pores and the imidization are synchronous, the operation is simple, and the cost is low. |
