低温碳化技术制备生物质多孔光热水蒸发复合材料及工艺参数对性能的影响
Preparation of Biomass Porous Photothermal Water Evaporation Composites by Low-temperature Carbonization and Effect of Process Parameters on Performance
摘要
Abstract
The article proposed a green and low-cost strategy based on the synergistic process of low-temperature carbonization and foaming,constructing a high photothermal-responsive porous evaporator only using wood flour,starch,and cuttlefish juice powder,and introducing polydopamine for surface modification.Through micro-morphology and solar-driven water evaporation performance test,the study investigated the effects of different carbonization temperatures,carbonization times,and material formula on the internal pore structure and solar-driven water evaporation performance of the composites.The results indicated that the low-temperature carbonization process could induce the thermal decomposition and expansion of starch to form irregular pores,which constructed a complete porous network for seawater transport and purification together with the inherent pores of pine wood fibers.The carbonization temperature and time determined the formation of the porous structure,while the content of cuttlefish juice powder significantly affected the photothermal response capability.When the mass ratio of wood flour,starch,and cuttlefish juice powder was 40∶50∶10,the carbonization temperature was 350℃,and the carbonization time was 2.0 h,the evaporator achieved the optimal pore structure and solar-driven water evaporation performance.The study provides a reference for the development and optimization of efficient solar-driven water evaporation materials.关键词
