To mimic the complexities of nature, surface chemistry for multifunctionalities has attracted attention. Here we adopt a post-spincoating modification method to obtain multi-chemical surface functionalities. The important step to form functionalities on surfaces is introducing chemical functional groups on a substrate by crosslinking polymers. To do so, we synthesized (2-thioxo-1,3-oxathiolan-5-yl)methyl methacrylate (DTCMMA) and copolymerized it with four different methacrylate monomers. 1,3-oxathiolane-2-thione is well-known to react with primary amine group. In this respect, we synthesized a crosslinker releasing amine groups upon light exposure. A double component system of the copolymer and the crosslinker was effectively crosslinked in thin film upon UV illumination. In addition, since the crosslinked polymer chains release thiol groups which could be further used to functionalize efficiently by effective chemistry, leading to the surfaces with multiple chemical functionalities.
