Displacer Effects on the Adsorption of Polystyrenes onto Nanoporous Silica |
| 초록 |
Understanding of polymer transport in nanopores is important for the advancement of chromatography and membrane-based separation techniques of polymers. The geometrical restriction of nanopore channels can impede the mobility of polymer chains confined in pores. In this report, we study the adsorption and transport of polystyrenes in solution using nanoporous silica. After pre-adsorbing the polystyrenes in nanoporous silica using cyclohexane solutions, low molecular weight displaces molecules are added to the solutions to understand how the solvent quality and surface affinity tuning by the displacer addition affects the adsorption and transports of the adsorptive chains confined in nanopores. Specifically, we aimed to elucidate how the adsorption of polymers in nanopores is different from that on “exposed” surfaces without geometric restrictions for the polymer adsorption. |
