| abstract |
The invention discloses a kind of preparation methods of tin oxide nano piece/polyaniline composite material.By SnCl 2 ยท2H 2 O and sodium citrate are dissolved in alcohol-water mixed solution, are transferred the solution into autoclave and are reacted 8 hours at 180 DEG C after mixing evenly, are cooled to room temperature, and are taken out product and are annealed at 400 DEG C in air 2 h, SnO is made 2 Nanometer sheet.Aniline monomer is added in the mixed solution of deionized water and hydrochloric acid, then by SnO 2 Nanometer sheet is added in mixed solution, is vigorously agitated again 20 min after 10 min of ultrasonic disperse, and mixed liquor is made.APS is dissolved in deionized water, gained APS solution is added dropwise in mixed liquor, reacts 12 h under nitrogen protection, is cleaned mixed liquor to neutrality with deionized water, is filtered, gained much filtrate is dried to arrive tin oxide nano piece/polyaniline composite material at 60 DEG C.Preparation process of the present invention is simple and environmentally-friendly, reliable, and raw material sources are extensive, low in cost, is especially suitable for industrialized production. |
