Polymeric microstructures and nanostructures can be prepared with use of a tip to pattern a surface. A tip can be used to pattern a structure which can initiate polymerization. The structure can be then exposed to monomer to induce polymerization at the structure. Alternatively, a tip can be used to pattern a surface with a monomer in which the surface is treated with polymerization catalyst so that polymerization occurs at the patterning site. Ring-opening metathesis polymerization can be carried out with use of the tip to control the polymerization. The tip can be a sharp tip as used in for example an atomic force microscope tip. Norbornene types of monomers can be used. Biological macromolecules can be also prepared.
聚合物微结构和纳米结构的制备可使用喷嘴对表面进行图案化。喷嘴可用于图案化可引发聚合的结构。然后将该结构暴露在单体中,诱导该结构发生聚合。另外,也可使用喷嘴用单体对表面进行图案化,在图案化部位使用聚合催化剂对表面进行聚合处理。开环偏聚聚合可通过使用喷嘴来控制聚合。针尖可以是尖锐的针尖,例如原子力显微镜的针尖。可以使用
