| 中文摘要: |
| 本研究以羧甲基纤维素钠(CMC-Na)和羧甲基壳聚糖(CMCS)为原料,制备了CMC-Na/CMCS气凝胶;将其与多孔铝网、铜箔组装,设计开发了具有“三明治”结构并兼具高效湿气捕获与转化能力的新型湿气发电装置(MEGs),考察了制得CMC-Na/CMCS气凝胶基MEGs的湿气发电性能。结果表明,CMC-Na与CMCS间成功发生交联反应,使制得的CMC-Na/CMCS气凝胶具备三维网络结构和均匀的孔隙。在温度45 ℃、相对湿度80%的条件下,CMC-Na/CMCS气凝胶基MEGs能输出的最大稳定开路电压(Voc)高达0.90 V,最大稳定短路电流(Isc)高达2.6 μA。在日常环境条件(温度25~40 ℃,相对湿度55%~75%)下,CMC-Na/CMCS气凝胶基MEGs能够实现长达24 h的持续电压输出,Voc稳定在0.43~0.79 V范围内,显示出良好的环境适应性和稳定性。 |
| Abstract: |
| In this study, carboxymethyl cellulose sodium (CMC-Na) and carboxymethyl chitosan (CMCS) were used as raw materials to prepare CMC-Na/CMCS aerogel. Then the aerogel was assembled with a porous aluminum mesh and copper foil to construct a novel moist electricity generation devices (MEGs) featuring a ‘sandwich’ structure that integrated both efficient moisture capture and conversion capabilities. The performance of moist electricity generation of prepared CMC-Na/CMCS aerogel-based MEGs was evaluated. The results indicated that the successful cross-linking between CMC-Na and CMCS was occurred, endowing the CMC-Na/CMCS aerogel with a three-dimensional network structure and uniform pore. Under conditions at 45 ℃ and relative humidity of 80%, the CMC-Na/CMCS aerogel-based MEGs achieved a maximum stable open-circuit voltage (Voc) of 0.90 V and a short-circuit current (Isc) of 2.6 μA. Under normal environmental conditions (temperature of 25~40 ℃, relative humidity of 55%~75%), the CMC-Na/CMCS aerogel-based MEGs sustained continuous voltage output for up to 24 h, with Voc stabilizing between 0.43 V and 0.79 V, demonstrating excellent environmental adaptability and operational stability. |
