以微水滴为模板和引发剂，采用气相聚合法制备了聚α-氰基丙烯酸乙酯中空微球。取决于壳厚度与半径的比率，中空微球在干燥期间将折叠以形成微球或微杯。这两种类型的微粒被用作构建块，以构建具有不同润湿性的表面。微球连接起来，形成一个多孔的网状表面，这是粗糙的，足以使表面超疏水性，而微杯构建的表面表现出较低的疏水性。此外，还得到了由两种微粒组成的表面，其粗糙度沿长度方向沿着逐渐减小，呈现出从超疏水到疏水的梯度润湿特性。由于聚α-氰基丙烯酸乙酯具有良好的生物相容性，所制备的超疏水或梯度润湿表面在生物医学领域具有潜在的应用前景。
Hollow microspheres of poly(ethyl α-cyanoacrylate) were prepared via vapor phase polymerization using micro-waterdroplets as template and initiator. Depending on the ratio of the shell thickness to the radius, the hollow microspheres would crimple to form either microballoons or microcups during drying. These two types of microparticles were used as building blocks to construct surfaces with diverse wettability. The microballoons linked up to form a porous-netlike surface which was rough enough to render the surface superhydrophobic, while the microcups-built surface showed less hydrophobicity. In addition, surfaces consisting of both microparticles with gradual decrease of roughness along the length direction were obtained, which presented gradient wetting property varied from superhydrophobic to hydrophobic. The as-formed superhydrophobic or gradient wetting surfaces may find potential applications in biomedical field because of the biocompatibility of poly(ethyl α-cyanoacrylate).
