TI  - Breaking The Permeance-Selectivity Tradeoff for Post-Combustion Carbon Capture: A 
      Bio-Inspired Strategy to Form Ultrathin Hollow Fiber Membranes.

AB  - Thin film composite (TFC) hollow fiber membranes with ultrathin selective layer 
      are desirable to maximize the gas permeance for practical applications. Herein, a 
      bio-inspired strategy is proposed to fabricate sub-100-nm membranes via a 
      tree-mimicking polymer network with amphipathic components featuring 
      multifunctionalities. The hydrophobic polydimethylsiloxane (PDMS) brushes act as 
      the roots that can strongly cling to the gutter layer, the PDMS crosslinkers 
      function as the xylems to enable fast gas transport, and the hydrophilic 
      ethylene-oxide moieties (brushes and mobile molecules) resemble tree leaves that 
      selectively attract CO(2) molecules. As a result, a  approximately 27 nm-thick selective layer 
      can be attached to the hollow fiber-supported PDMS gutter layer through a simple 
      dip-coating method without any modification. Furthermore, a CO(2) permeance of 
       approximately 2700 GPU and a CO(2) /N(2) selectivity of  approximately 21 that is beyond the 
      permeance-selectivity upper bound for hollow fiber membranes is achieved. This 
      bio-inspired concept can potentially open the possibility of scalable hollow 
      fiber membranes production for commercial applications in post-combustion carbon 
      capture and beyond.
