      Membranes with Outstanding Pervaporation Performance.

AB  - Poly(dimethylsiloxane) (PDMS) membranes are widely used for bioethanol 
      separation. However, the network cavity size r(3) of PDMS membranes is generally 
      smaller than the ethanol kinetic radius (0.225 nm), which limits the transport of 
      ethanol molecules and weakens the pervaporation performance. Herein, we proposed 
      a particle-driven, ultrafast-cured strategy to overcome the above key issue: (1) 
      Incorporating particles into PDMS for preventing polymer chains from packing 
      tightly, (2) freezing particles within a PDMS layer by the ultrafast 
      UV-cross-linking for improving its distribution and increasing the chain 
      extension of the polymer, and (3) covalently bonding particles with PDMS to 
      enhance their compatibility. Consequently, r(3) was increased to 0.262 nm, and an 
      extremely high loading membrane (50 wt %) with an ultrashort curing time (20 s) 
      was prepared, which is difficult to be realized by the conventional thermally 
      driven approach. As a result, a separation factor of 13.4 with a total flux of 
      2207 g m(-2) h(-1) for separating ethanol from a 5 wt % aqueous solution at 60  degrees C 
      was obtained. This strategy shows the feasibility of recovery of different 
      bioalcohols and the large-scale continuous membrane preparation.
