In recent years, dopamine has attracted much attention as a surface modifier that can be widely used in biological, electrochemical and membrane applications. We herein report a pH-responsive polydimethylsiloxane (PDMS) platform modified with polydopamine nanospheres (PDA Ns). PDMS has excellent optical transparency and elasticity, good biocompatibility and good insulation. We prepared PDMS platform on microscope slides and grafted the polydopamine nanospheres to make it rough and obtained the superhydrophobic structure. The test shows the modified rough structure is stable and pH responsive.
