以聚甲基丙烯酸甲酯(PMMA)为掺杂剂,过硫酸铵(APS)为氧化剂合成PANI/PMMA复合物.该复合物是以PMMA为核,以PANI为表层的新型聚合物,检测表明在室温下对氨气有较好的灵敏度.通过控制变量法,考察了不同制备因素对PANI/PMMA乳液稳定性及其复合材料气敏性能的影响,初步确定了试验中各反应物的用量范围和实验条件:n(DKSA)/n(AN)=1.5,n(APS)/n(AN)=1.2,w(PMMA)/w(AN)=4;聚合时间为18h.
以聚甲基丙烯痠甲酯(PMMA)為摻雜劑,過硫痠銨(APS)為氧化劑閤成PANI/PMMA複閤物.該複閤物是以PMMA為覈,以PANI為錶層的新型聚閤物,檢測錶明在室溫下對氨氣有較好的靈敏度.通過控製變量法,攷察瞭不同製備因素對PANI/PMMA乳液穩定性及其複閤材料氣敏性能的影響,初步確定瞭試驗中各反應物的用量範圍和實驗條件:n(DKSA)/n(AN)=1.5,n(APS)/n(AN)=1.2,w(PMMA)/w(AN)=4;聚閤時間為18h.

PMMA/PANI composites was synthesized by polymethyl methacrylate (PMMA) as the dopant and am-monium persulfate (APS) as oxidant. The new polymer regarded PMMA as the nuclear and PANI as the surface layer. The results showed that the polymer had a high sensitivity to NH_3 under the room temperature. The impact of different factors on the stability of PANI/PMMA emulsion and gas sensitivity property of composites was studied by controlling the variables. The dosage of reactant and experimental conditions were decided preliminary: n(DBSA)/n(AN)= 1.5;n(APS)/ n (AN)=1.2;w (PMMA)/w(AN)=4.
