摘要： Methods for surface treatment of polyester substrates are described. Treatment methods include adherence of a polymer layer on a surface of the polyester so as to increase the hydrophilic properties of the surface. Polymers can be polyelectrolytes that are adsorbed at the surface or polymer brushes that are polymerized at the surface. Further surface functionalization can include the adherence of inorganic nanoparticles to the surface. The polyester substrates can be recycled polyester such as recycled polyethylene terephthalate that has been subjected to a partial saponification reaction during the recycling process.
