Linear or star block copolymers (BCPs) generally have incompatible segments because of their different physical and chemical property. But due to the covalent bonds between the segments, BCPs perform micro-scale and orderly microphase separation in the bulk, thin film, and solution states. This process is so-called self-assembly and attain microphase separations which provide a variety of applications. Star-like polymers have recently been a novel research topic and applications. In this project, we focus in a special material of [polystyrene-block-poly(2-vinylpyridine)]4 ([PS-b-P2VP]4) 4-arm star-shaped BCPs. We will use TEM, SAXS, AFM, DLS, and other instruments to observe their self-assembly behaviors. After processing the BCPs, it will be investigated the adsorption behaviors of heavy metals (Au, Ag, Pd, Pt, Cr) in different conditions (e.g., temperature, pressure, pH). |
