Smart l-borneol-loaded hierarchical hollow polymer nanospheres with antipollution and antibacterial capabilities

Porous organic polymers having well-defined morphologies and designable functionalities are potentially suitable materials for environmental remediation, e.g., for the removal of pollutants from water. However, single materials generally do not simultaneously possess high adsorption abilities and antibacterial performance, as well as easy processibility. Herein, we reported a processible porous polymer which composed swellable hollow spherical morphology and branched L-borneol antibacterial agents. These features endure a valuable capability of pollutant absorption for represented pollutants such as, organic dye (methylene blue), organic compound (bisphenol A), and the heavy metal (Cu 2+ ). In addition, the L-borneol groups and 3D crosslinked hierarchical structure result in enhancement of antibacterial performance against Escherichia coli and Staphylococcus aureus . Moreover, we demonstrate the preparation of the polymer as a fine powder could anchored on the membranes, processed into the tablet, adhered with the polyurethane foams, and assembled as the dye absorption device. The rationally designed polymers by this method show notable potential as adsorbents for water purification and sewage treatment.
