The article reports a two-step synthesis of composite nanofibrous mats of polytetraflouroethylene/zinc oxide (PTFE-ZnO); first, emulsion electrospinning of precursor solution was performed to yield as-spun mats followed by heat treatment at 280 °C. The surface of pure PTFE nanofibrous mats was modified by varying the amount of ZnO loadings in the electrospinning solution from 10 to 20 wt.%. Physiochemical characterization of synthesized mats was performed by FESEM, EDX, AFM, FTIR, Raman, TGA and contact angle goniometry. It was observed that fiber mean diameter decreased from 0.243 ± 15.10 μm to 0.17 ± 30.50 μm, RMS roughness increased from 112 to 627 nm and CA improved from 102.56° to 121.55° with the rise in ZnO content up to 20 wt% compared to the pure PTFE mats. Higher surface area, roughness and hydrophobicity of PTFE-ZnO mats resulted into significantly enhanced adsorption ability of VOCs on their surfaces against three model VOCs, namely, toluene, acetone and formaldehyde. The results have demonstrated that surface adsorption capacity of tested VOCs has considerably increased to 10, 07 and 03 folds respectively for the nanofibrous mats containing 20 wt.% ZnO, compared to pure PTFE mats. Based on these findings, these nanofibrous mats can potentially be used as filters for VOCs and particulate removal from air in the processing industries.

该文章报道了聚四氟乙烯/氧化锌（PTFE-ZnO）复合纳米纤维垫的两步合成；首先，进行前体溶液的乳液静电纺丝以生产初纺垫，然后在280°C进行热处理。通过将电纺丝溶液中的ZnO负载量从10重量％更改为20重量％，可以对纯PTFE纳米纤维毡的表面进行改性。通过FESEM，EDX，AFM，FTIR，拉曼，TGA和接触角测角法进行了合成席子的理化表征。观察到，随着ZnO含量增加至20 wt％，纤维平均直径从0.243±15.10μm减小至0.17±30.50μm，RMS粗糙度从112增加至627 nm，CA从102.56°改善至121.55°。纯PTFE垫。较高的表面积 PTFE-ZnO毡的粗糙性和疏水性导致VOC在其表面上对三种模型VOC（即甲苯，丙酮和甲醛）的吸附能力大大增强。结果表明，与纯PTFE毡相比，含20％（重量）ZnO的纳米纤维毡的经测试VOC的表面吸附能力分别显着提高至10倍，07倍和03倍。基于这些发现，这些纳米纤维垫可以潜在地用作加工业中空气中VOC和微粒去除的过滤器。与纯PTFE垫相比，含20％（重量）ZnO的纳米纤维垫的折叠分别为07和03倍。基于这些发现，这些纳米纤维垫可以潜在地用作加工业中空气中VOC和微粒去除的过滤器。与纯PTFE垫相比，含20％（重量）ZnO的纳米纤维垫的折叠分别为07和03倍。基于这些发现，这些纳米纤维垫可以潜在地用作加工业中空气中VOC和微粒去除的过滤器。
