TI  - Superhydrophobic Hybrid Paper Sheets with Janus-Type Wettability.

AB  - We introduce the design of Janus-type paper sheets where one side of the paper 
      exhibits superhydrophobic properties, whereas the other side of the sheet remains 
      hydrophilic and therefore can take up aqueous solutions by capillary wicking. 
      Such papers are being prepared by chemically immobilizing a thin hybrid coating 
      on paper sheets that consists of cross-linked poly(dimethylsiloxane) (PDMS) and 
      inorganic particles of various sizes ranging from nanometers to several tens of 
      micrometers. Both commercially available Whatman No. 1 filter paper and 
      lab-engineered cotton linters-based paper substrates were treated with this 
      approach. The hybrid paper sheets have high chemical durability, mechanical 
      stability, and flexibility because of a covalent attachment of the particles to 
      paper fibers and the inherent elasticity of PDMS chains. In spite of the 
      superhydrophobicity of the coating, the untreated side of the paper substrates 
      preserved its hydrophilicity, resulting in Janus-type wetting and wicking 
      properties, respectively. The functionalized paper samples remained porous and 
      permeable to gases, while possessing a gradual change in chemistry between the 
      two sides exhibiting a dramatic wetting contrast. Such two-sided properties open 
      up new applications for such hybrid paper materials, such as in wound dressings 
      and/or bandages with a liquid directing and confinement ability.
