摘要
探索具有优异光热转换功能的新型材料用于太阳能光热蒸发水被认为是同时实现直接和充分利用广泛分布的太阳能和缓解世界淡水匮乏的理想策略.通过亲水性杂多蓝(HPB,H3PMo12O40)和疏水性表面活性剂(双十八烷基二甲基溴化铵,DODA)的自组装制备了一种两亲性光热膜.基于二维DODA-HPB自组装的柔性膜(DODA-HPB/Nylon66)得益于功能性亲水HPB层和疏水DODA层交替出现的协同效应,表现出优异的光热转换性能,在太阳能海水淡化和废水处理方面具有广阔的应用前景.
Abstract
Exploring novel materials with excellent photothermal conversion capabilities for solar photo-thermal water evaporation is considered as an ideal strategy to simultaneously realize the direct and full use of the widely distributed solar energy and alleviate the world's freshwater scarcity.Herein,an amphiphilic photothermal membrane is prepared through the self-assembly of hydrophilic heteropoly blue(HPB,H3PMo12O40)and hydrophobic surfactant(dioctadecyl dimethyl ammonium bromide,DODA).Benefiting from the synergistic effects of alternating functional hydrophilic HPB and hydrophobic DODA layers,the flexible membrane based on two-dimensional DODA-HPB self-assemblies(DODA-HPB/Nylon66)exhibits superior photothermal conversion properties,showing promising prospects in applications of solar desali-nation and wastewater treatment.
