Massive production of SiO₂ nanofibers with both high durability and exceptional performance remains a significant challenge. Herein, a novel approach was introduced to achieve the massive production of SiO₂ nanofibers with lotus-leaf-inspired surfaces by combining solution blowing spinning (SBS) and the polymer-derived ceramics method. Based on the SBS technique, three types of precursor nanofiber products were fast spined with methyl silsesquioxane polymer and polymethyl hydrogen siloxane employed as Si sources. The flow rate of the SBS spined Si-based ceramic nanofibers was enhanced to 20 mL·h^–1. Furthermore, through the integration of hydrophobic-oleophilic SiO₂ nanoparticles into the precursor solution, SiO₂ nanofibers with lotus-leaf nanoprotrusion surfaces were fabricated. Nanoparticle-decorated SiO₂ fibers demonstrated excellent hydrophobicity (138.3°), compression resilience (∼60%), proficiency in organic pollutant adsorption, high-temperature resistance (∼1100 °C), and outstanding thermal insulation properties (thermal conductivity of 0.0165 W·(m·K)⁻¹).

大规模生产兼具高耐用性和卓越性能的 SiO ₂纳米纤维仍然是一个重大挑战。在此，提出了一种新方法，通过将溶液吹制纺丝（SBS）与聚合物衍生陶瓷方法相结合，实现了具有荷叶状表面的SiO ₂纳米纤维的大规模生产。基于SBS技术，以甲基倍半硅氧烷聚合物和聚甲基氢硅氧烷为硅源，快速纺丝出三种类型的前驱体纳米纤维产品。 SBS纺丝硅基陶瓷纳米纤维的流速提高至20 mL·h ^–1。此外，通过将疏水亲油的SiO ₂纳米粒子整合到前驱体溶液中，制备了具有荷叶状纳米突起表面的SiO ₂纳米纤维。纳米颗粒修饰的SiO ₂纤维表现出优异的疏水性（138.3°）、压缩回弹性（∼60%）、良好的有机污染物吸附能力、耐高温（∼1100 °C）和出色的隔热性能（导热系数为0.0165 W） ·(m·K) ^-1 )。
