Abstract
- Inspired by the surface self-assembly modification technique using dopamine, herein, a polydopamine (pDA)-modified nanocomposite was successfully obtained on the surfaces of TiO2 (pDA@TiO2). The key design of the as-reported ibuprofen-imprinted nanocomposite membranes (IINCMs) was the composite integration process of pDA@TiO2 and porous polyvinylidene fluoride (PVDF) membranes, in which the pDA@TiO2 was used as functional microspheres. As such, the novel porous IINCMs were developed and synthesized through a simple sol–gel method by using ibuprofen as the template molecule. Importantly, the as-prepared pDA-coating layers on TiO2 could largely enhance the rebinding capacity of IINCMs, and contribute to the blended functional pDA@TiO2 microspheres, and the as-prepared IINCMs revealed an outstanding adsorption amount (42.14 mg g−1) and regenerability. In addition, an excellent permselectivity performance (the βketoprofen/ibuprofen and βnaproxen sodium/ibuprofen were 4.42 and 4.46, respectively) could be achieved, which was beneficial for the adsorption and separation of ibuprofen.
