Polystyrene-block-Poly(n-pentyl methacrylate)(PS-b-PnPMA) is focused because it is the only block copolymer having baroplasticity. So we can easily transit order to disorder by using pressure. We made nanoparticles/PS-b-PnPMA composite to fabricate nano-circuit. To put nanoparticles into one block, we synthesized gold nanoparticles decorated with 11-mercapto-1-undecanol because they can induce polar-polar interaction with PnPMA block. This array have conductivity because distance between nanoparticles is very close. However, after putting pressure on composite material, it is changed from ordered state to disordered state. Then, disordered state materials do not have conductivity. In this method, we can alter current intensity by changing inter-distance between nanoparticles. Therefore, it is possible to fabricate nano-scaled circuit using only pressure. |
