TI  - Functionalization and Surface Modification of Mesoporous Hydrophobic Membranes by 
      Oligomers and Target Additives via Environmental Crazing.

AB  - This work offers an ecologically friendly and facile approach for the 
      modification of high-tonnage commercial polymers, including polypropylene (PP), 
      high-density polyethylene (HDPE), and poly(ethylene terephthalate) (PET), and 
      preparation of nanocomposite polymeric membranes via incorporation of modifying 
      oligomer hydrophilic additives, such as poly(ethylene glycol) (PEG), 
      poly(propylene glycol) (PPG), polyvinyl alcohol (PVA), and salicylic acid (SA). 
      Structural modification is accomplished via the deformation of polymers in PEG, 
      PPG, and water-ethanol solutions of PVA and SA when mesoporous membranes are 
      loaded with oligomers and target additives. The content of target additives in 
      nanocomposite membranes is controlled by tensile strain, and the level of loading 
      can achieve 35-62 wt.% for PEG and PPG; the content of PVA and SA is controlled 
      by their concentration in the feed solution. This approach allows for the 
      simultaneous incorporation of several additives which are shown to preserve their 
      functional performance in the polymeric membranes and their functionalization. 
      The porosity, morphology, and mechanical characteristics of the prepared 
      membranes were studied. The proposed approach allows an efficient and facile 
      strategy for the surface modification of hydrophobic mesoporous membranes: 
      depending on the nature and content of target additives, their water contact 
      angle can be reduced to 30-65 degrees . Water vapor permeability, gas selectivity, 
      antibacterial, and functional properties of the nanocomposite polymeric membranes 
      were described.
