针对目前有机硅平滑剂乳液往往存在分散稳定性差或高剂量表面活性剂引起的应用性能降低等问题,以聚丙烯酸异辛酯的共聚物胶乳(PEHA)为Pickering颗粒,协同表面活性剂,用于制备“油/水”Pickering有机硅乳液,并将其用于织物后整理。考察了PEHA粒径、表面亲水改性及PEHA质量分数对有机硅乳液分散稳定性的影响,通过对整理残液化学需氧量(COD)和整理织物表面摩擦因数的研究,考察了表面活性剂与Pickering纳米颗粒协同稳定对有机硅乳液应用性能的影响。结果表明:PEHA颗粒吸附在有机硅液滴的表面,形成机械阻隔,提升有机硅乳液的分散稳定性,180 nm的PEHA颗粒的稳定效率最佳,90 nm时的稳定效率最差;表面亲水改性能显著提高PEHA稳定乳液的效率,在质量分数仅为10%时,即可实现乳液稳定;最佳稳定方案可使表面活性剂质量分数降低60%以上;浸轧整理织物时,相比表面活性剂独自稳定的体系,Pickering体系吸附织物效率更高,整理后残液的COD值降低63%,整理织物表面静、动摩擦因数分别降低至0.51与0.49,即“Pickering/表面活性剂”协同稳定有机硅乳液具有良好的应用性能。

本文利用三氧化钼(MoO_3)/金(Au)作为二硫化钼(MoS2)场效应晶体管的电极,得到了接触改善的N型二硫化钼场效应晶体管,并对其输运性质进行了变温测量.研究发现,将氧化钼作为在二硫化钼与金属电极之间的过渡层,可以很好地改善二硫化钼场效应器件的肖特基接触:对于2nm厚度的二硫化钼,其室温迁移率可达25cm2V^(–1)s^(–1),与没有三氧化钼接触的器件相比,室温迁移率提高了近16倍;对于8nm厚度的二硫化钼,其低温迁移率最高可达100cm^2V^(–1)s^(–1).优化后的电接触使得我们可以提取出二硫化钼器件本征的低温输运特性,并发现缺陷杂质对载流子的散射是影响器件输运性质的主要原因;其中在少层二硫化钼中,缺陷杂质的散射作用随着载流子浓度的增加、屏蔽能力的增强而减少.这种改善接触的方法同样适用于其他过渡金属硫族化合物.
