【摘要】:石墨烯獲得2010的諾貝爾獎(jiǎng)之后引起了研究者的廣泛關(guān)注,隨著對(duì)石墨稀性能的深入研究,發(fā)現(xiàn)石墨烯的電學(xué)性能和穩(wěn)定性是其他材料所不完全具備的。聚苯胺作為三大導(dǎo)電高分子材料之一,雖然具有很好的導(dǎo)電性但是穩(wěn)定性并不樂觀,限制了聚苯胺的應(yīng)用,于是本文圍繞這兩種材料的電學(xué)性能和穩(wěn)定性做了一些研究,以實(shí)現(xiàn)二者的優(yōu)勢(shì)互補(bǔ)。1.首先本論文研究了一種水性聚苯胺封裝石墨烯材料的制備方法,并將該材料應(yīng)用于防靜電涂料,測(cè)試了其防靜電的性能,結(jié)果顯示其具有很好的防靜電作用,能夠滿足工業(yè)應(yīng)用標(biāo)準(zhǔn),并且具有很好的穩(wěn)定性,是一種環(huán)境友好型防靜電涂料。2.其次本論文報(bào)告了一種簡(jiǎn)單的方法,通過直接的原位聚合制備石墨烯/聚苯胺(G/PANI)纖維。并將兩根纖維在H2SO4-PVA電解質(zhì)中浸泡,得到全固態(tài)的石墨烯/聚苯胺超級(jí)電容器,將該超級(jí)電容器固定于PET薄膜上可以得到柔性的全固態(tài)超級(jí)電容器,并對(duì)該全固態(tài)超級(jí)電容器性能做出了測(cè)試。3.最后本論文針對(duì)第二部分的制備方法做出了改進(jìn),采用更環(huán)保的電化學(xué)方法制備了聚苯胺封裝石墨烯纖維的超級(jí)電容器電容材料,并對(duì)該材料的電容性能和循環(huán)穩(wěn)定性做了測(cè)試,最后為了得到更高的循環(huán)穩(wěn)定性,本文又研究了電容損失的原因,并采用低電壓窗口的方法避免了電容的損失,得出了更好的循環(huán)穩(wěn)定性。
[Abstract]:After winning 2010 Nobel Prize, graphene has attracted extensive attention of researchers, with the further study of graphite dilute properties, It is found that the electrical properties and stability of graphene are not completely possessed by other materials. Polyaniline, as one of the three conducting polymer materials, has good electrical conductivity, but its stability is not optimistic, which limits the application of Polyaniline. In this paper, the electrical properties and stability of the two materials are studied in order to realize the complementary advantages of the two materials. Firstly, the preparation method of a waterborne Polyaniline encapsulated graphene material is studied in this paper. The material is applied to antistatic coating, and its antistatic performance is tested. The results show that the material has good antistatic effect, can meet the industrial application standard, and has good stability. This paper reports a simple method to prepare graphene / Polyaniline G / PANIfiber by direct in situ polymerization and immerse the two fibers in H2SO4-PVA electrolyte. An all-solid-state graphene / Polyaniline supercapacitor is obtained. A flexible all-solid supercapacitor can be obtained by fixing the supercapacitor onto a PET film. The performance of the all-solid supercapacitor was tested. Finally, the preparation method of the second part was improved, and the Polyaniline supercapacitor material encapsulated graphene fiber was prepared by a more environmentally friendly electrochemical method. The capacitance performance and cycle stability of the material are tested. Finally, in order to obtain higher cycle stability, the reason of capacitance loss is studied, and the loss of capacitance is avoided by using the method of low voltage window. A better cycle stability is obtained.
