Abstract

A simple route towards patchy particles with anisotropic patches with respect to a different functionality and directionality is presented. This method is based on microcontact printing of positively charged polyethylenimine (PEI) on silica particles using wrinkled stamps. Due to the wrinkled surface, the number of patches on the particles as well as the distance between two patches can be controlled.

摘要

提出了一种简单的方法来制备具有各向异性补丁的斑驳颗粒，这些补丁在不同的功能和方向上具有各向异性。该方法基于使用褶皱印章将带正电的聚乙烯亚胺（PEI）微接触印刷到二氧化硅颗粒上。由于褶皱表面，颗粒上的补丁数量以及两个补丁之间的距离都可以得到控制。
