In this study, cellulose nanocrystals hollow microspheres (HMs) were fabricated through Pickering emulsion polymerization, in which hydrophobically modified cellulose nanocrystals (CNCs) acted as Pickering stabilizers. The hollow interior core was prepared by solvent evaporation. This manuscript describes the synthesis of HMs in detail. The hollow structure and nanoscale size of HMs were verified using TEM. The resultant HMs could easily coat self-forming films on the surface of PET fabrics. Additionally, these coatings exhibited superior breathability and moisture permeability properties with a high one-way transport index of 936.33% and a desirable overall moisture management capability of 0.72. Cellulose nanocrystal hollow microsphere coatings could be used as a moisture-wicking functionality agent for finishing fabrics, oil-water separation, and fog harvesting.
在本研究中，通过皮克林乳液聚合制备了纤维素纳米晶体空心微球（HMs），其中疏水改性的纤维素纳米晶体（CNCs）作为皮克林稳定剂。通过溶剂蒸发制备中空内芯。本手稿详细描述了HMs的合成。使用透射电子显微镜（TEM）验证了HMs的中空结构和纳米级尺寸。所得的HMs能够轻松地在聚酯（PET）织物表面形成自形成膜。此外，这些涂层表现出优异的透气性和透湿性，单向传输指数高达936.33%，整体吸湿排汗能力良好，为0.72。纤维素纳米晶体空心微球涂层可用作织物整理的吸湿排汗功能剂、油水分离和雾气收集。
