Various hydrophobic hairy carbonaceous fibers are obtained by a low-temperature CVD process on catalyst-patterned surface patches which are selectively coated with silica to make the surface superhydrophobic and yet allow strong water adhesion for the "Salvinia effect". The versatility of the functional hairy fiber surfaces is demonstrated with a liquid barrier grid for cell microarray, a gas retaining capability under water/liquid for a membrane-free microfluidic chemical process, and functionalized papillae for cell immobilization with green algae.
通过在催化剂图案化的表面斑块上进行低温 CVD 工艺，可以获得各种疏水性毛绒状碳纤维，这些表面斑块选择性地涂覆有二氧化硅，从而使表面具有超疏水性，但又能为“Salvinia 效应”提供强烈的水附着力。功能性毛绒纤维表面的多功能性通过用于细胞微阵列的液体阻挡栅格、在水/液体下保持气体的能力的无膜微流控化学工艺以及用于固定绿藻的功能化乳突来展示。
