Interfacially crosslinked β-cyclodextrin polymer composite porous membranes for fast removal of organic micropollutants from water by flow-through adsorption.

Persistent organic micropollutants have seriously damaged aquatic ecological equilibrium and affected human health. Conventional adsorbents are limited due to slow adsorption rate. Therefore, it's significant to integrate adsorbent into porous membrane to develop a highly efficient continuous filtration method for water purification.

Macroporous membranes doped with micro-mesoporous β-cyclodextrin polymers for ultrafast removal of organic micropollutants from water.

Herein, we report novel macroporous membranes doped with micro-mesoporous β-cyclodextrin polymers (β-CDP), named β-CDP membranes, for water decontamination by the flow-through process. These membranes combine excellent adsorption behavior of β-CDP and the advantages of membranes filtration including low energy consumption and easy scale-up. Filtration adsorption results demonstrated that the optimal β-CDP membrane removed > 99.

Achieving a Collapsible, Strong, and Highly Thermally Conductive Film Based on Oriented Functionalized Boron Nitride Nanosheets and Cellulose Nanofiber.

Boron nitride nanosheet (BNNS) films receive wide attention in both academia and industry because of their high thermal conductivity (TC) and good electrical insulation capability. However, the brittleness and low strength of the BNNS film largely limit its application. Herein, functionalized BNNSs (f-BNNSs) with a well-maintained in-plane crystalline structure were first prepared utilizing urea in the aqueous solution via ball-milling for the purpose of improving their stability in water and enhancing the interaction with the polymer matrix.
