Directed nanoparticle binding onto microphase-separated block copolymer thin films

The binding of gold nanoparticles onto microphase-separated polymeric films deposited on surfaces, where hydrogen bonding interaction was positioned in the polymeric blocks of a block copolymer (BCP) was investigated. It was found that the synthesis of the BCP relied on a previously developed combination of ROMP homopolymers with 'click type' reactions, furnishing the corresponding BCP-1 in high yields. Phase separation was achieved through a defied molecular design of the block copolymer BCP-1 and clearly seen upon generating films on silicon wafers and thermal annealing. The results show that selective nanoparticle binding could effect on specific regions of the BCP film, in particular those displaying the Hamilton receptor.
