This research aims to create a high-efficiency, low-resistance biodegradable air-filter structure containing beeswax as a result of the simultaneous production of fibers by solution-blowing and melt-blowing. The melt-blowing method is effective for producing micrometer fibers on an industrial scale. In turn, the solution-blowing method allows for the production of fibers with a nanometric diameter from solutions containing temperature-sensitive additives such as beeswax. Combining these two methods is a promising perspective for producing high-performance, functional air-filter materials. Beeswax is a natural material capable of accumulating an electrical charge. When an external electric field is applied, the presence of beeswax in the filter structure facilitates charge retention on the fiber surface. This results in a fully biodegradable filter material with high efficiency and low resistance.
本研究旨在通过溶液吹塑和熔喷同时生产纤维，创建一种包含蜂蜡的高效、低阻可生物降解空气过滤结构。熔喷法对于在工业规模上生产微米级纤维是有效的。反过来，溶液吹塑法允许从含有蜂蜡等温度敏感添加剂的溶液中生产纳米直径的纤维。将这两种方法结合起来是生产高性能、功能性空气过滤材料的一个有前景的方向。蜂蜡是一种能够积累电荷的天然材料。当施加外部电场时，过滤结构中蜂蜡的存在有助于电荷保留在纤维表面。这产生了一种具有高效率和低阻力的完全可生物降解的过滤材料。
