As a pest, locusts have caused great economic loss and ecological damage. However, locusts are rich in protein, and the functional components of protein have a high utilization value. Herein, a source material of air filtration membrane (WP/BC/ILP) for particulate matter (PM) were prepared by blending isolated locust protein (ILP), bacterial cellulose (BC), and micron-sized wood pulp fiber (WP). This WP/BC/ILP exhibited favorable mechanical properties after optimization experiments, maintaining considerable filtration efficiency even as air flow rates varied. Under different pollutant concentrations, the WP/BC/ILP had high and stable filtration efficiency for PM with different particle sizes. In addition, the WP/BC/ILP was prepared with biodegradable material a simple production method without organic solvents. This study prospectively provides a reasonable method for utilizing locust protein and a strategy for the source materials with high efficiency and environmental protection air filters.

制备刺槐蛋白和纤维素复合材料作为空气过滤膜制造的天然原料


蝗虫作为一种害虫，造成了巨大的经济损失和生态破坏。但蝗虫富含蛋白质，蛋白质的功能成分具有很高的利用价值。在此，通过将分离的刺槐蛋白（ILP）、细菌纤维素（BC）和微米级木浆纤维（WP）共混，制备了用于颗粒物（PM）的空气过滤膜（WP/BC/ILP）的原材料。经过优化实验后，该 WP/BC/ILP 表现出良好的机械性能，即使在空气流量变化的情况下也能保持相当大的过滤效率。在不同污染物浓度下，WP/BC/ILP对不同粒径的PM均具有较高且稳定的过滤效率。此外，WP/BC/ILP采用可生物降解材料制备，生产方法简单，无需有机溶剂。本研究前瞻性地为刺槐蛋白的利用提供了合理的方法，并为高效环保空气过滤器的原料来源提供了策略。
