亚微米聚合物生产领域目前的主要研究重点是形态和应用。相比之下，对亚微米聚合物纤维制造的可持续性，特别是能源效率的探讨较少。绿色化学和绿色工程的原则概述了制造“绿色”产品的框架，这两个框架中最重要的原则集中在能源效率、材料浪费和无害材料的使用。本研究研究了在通过压力纺丝生成纤维的关键成型参数的大小下，生产聚环氧乙烷 (PEO) 和聚乙烯吡咯烷酮 (PVP) 亚微米纤维期间的功耗。纤维制造过程中的能耗、纤维直径和生产率主要取决于所用聚合物溶液的特性。聚合物纤维是关键的工程材料，但它们也带来了环境挑战。该研究调查了使用聚环氧乙烷（PEO）和聚乙烯吡咯烷酮（PVP）的可持续生产，强调绿色工程原理。 PVP 表现出更好的能源效率和更高的生产率，但 PEO 产生的纤维直径更小，通过加压回转生产的两种聚合物在 35% 浓度和 0.2 MPa 压力下实现了最佳控制。
The field of submicrometer polymeric production currently has a predominant research focus on morphology and application. In comparison, the sustainability of the manufacture of submicrometer polymeric fibers, specifically the energy efficiency, is less explored. The principles of Green Chemistry and Green Engineering outline frameworks for the manufacture of “greener” products, where the most significant principles in the two frameworks are shown to be centered on energy efficiency, material wastage, and the use of non‐hazardous materials. This study examines the power consumption during the production of Polyethylene oxide (PEO) and Polyvinylpyrrolidone (PVP) submicrometer fibers under magnitudes of the key forming parameters to generate fibers via pressure spinning. The energy consumption, along with the fiber diameter, and production rate during the manufacture of fibers is predominantly attributed to the characteristics of polymeric solutions utilized. Polymeric fibers are key engineering materials, however, they present environmental challenges. The study investigates sustainable production using Polyethylene oxide (PEO) and Polyvinylpyrrolidone (PVP), emphasizing green engineering principles. PVP exhibited better energy efficiency and higher production rates, however PEO generated smaller diameter fibers, with optimal control achieved at 35% concentration and 0.2 MPa pressure for both polymers produced via pressurized gyration.
