层状二氧化锰的剥层组装及其作为紫外屏蔽材料的性能研究
|
摘要
采用水热法制备了层间阳离子为钠离子的层状MnO_2(Bir(Na))前体，通过离子交换法将氢离子交换到层间，得到的氢型MnO_2(Bir(H)在四甲基氢氧化铵作用下离心剥离，得到了MnO_2纳米片溶胶。MnO_2纳米片溶胶分别与十二烷基三甲基氯化铵、十四烷基三甲基氯化铵、十六烷基三甲基氯化铵、十八烷基三甲基氯化铵、双十八烷基二甲基氯化铵、十二烷基苄基二甲基氯化铵、十八烷基苄基二甲基氯化铵通过静电作用组装，得到超分子插层结构的烷基铵阳离子-二氧化锰(RNH_3-MnO_2)，并采用X-射线衍射、傅立叶红外光谱、热重-差热、透射电镜、场发射扫描电镜等手段，对产物进行了表征。
通过熔融混炼法制备了烷基铵阳离子-二氧化锰／聚烯烃塑料纳米复合材料。双十八烷基二甲基铵阳离子-二氧化锰／聚乙烯(2C18-MnO_2／PE)纳米复合材料在200-400 nm的紫外区有良好的紫外屏蔽性能，且在可见光区有很好的透过率。对比研究了十八烷基三甲基铵阳离子-二氧化锰／聚乙烯(C18-MnO_2／PE)复合材料及Bir(H)／PE复合材料。超分子插层结构MnO_2在混炼过程中剥离成为纳米片，由于纳米片的纳米效应表现出前体材料所不具有的紫外屏蔽性能。
Layered manganese oxide(Bir(Na)) is synthesized by hydrothermal method. Layered manganese oxide with H~+ in the interlayer(Bir(H)) is obtained by ion-exchange progress between Bir(Na) and H~+. After soaking in tetramethylammonium(TMA) solution, Bir(H) is delaminated into nanosheet slurry. By a delamination/assembly progress, the nanosheet slurry is reassembled with n-dodecyl trimethylammonium chloride, n-tetradecyltrimethyl-ammonium chloride, n-hexadecyl trimethylammonium chloride, n-octadecyl trimethylammonium chloride, n-dioctadecyl dimethylammonium chloride, benzyl dodecyldimethylammonium chloride and benzyl octadecyldimethyl-ammonium chloride, respectively. The obtained products are supramolecular intercalated structure and investigated by X-ray diffraction(XRD) analysis, Fourier transform infrared(FT-IR) analysis, Thermogravimetry-Differential thermal(TG-DTA) analysis, Transmission electron microscopy(TEM) analysis and Field emission scanning electron microscopy(FESEM) analysis.
The alkylammonium-MnO_2/polyolefin nanocomposites are obtained by melt-compounding progress. The dioctadecyl dimethylammonium-MnO_2/ polyethylene nanocomposite has excellent UV-blocking property and improved thermal stability. The n-octadecyl trimethylammonium-MnO_2/ polyethylene and Bir(H)/polyethylene nanocomposites are also studied as a contrast to dioctadecyl dimethylammonium-MnO_2/polyethylene. Manganese oxide with supramolecular intercalated structure is delaminated into nanosheet during the melt-compounding progress, and the nanosheet show the UV-blocking property that is different from the bulk material because of Nano effect.
