A simple approach for surface hardening of polystyrene
One strategy in prolonging the lifetime of polymer materials is to improve their surface mechanical properties. A simple and easy method to modify the polymer surface based on the preferential segregation of inorganic materials is applied to a glassy polymer. We clearly show that the polystyrene film with a few nm-thick hybrid surface layer with hydrolyzed tetraethoxysilane exhibits excellent wear resistance and anti-oxidant properties. âº A simple method to improve surface properties is applied to glassy polymers. âº Hydrolyzed TEOS was preferentially segregated at the surface of polystyrene. âº A few nm-thick polymer–inorganic hybrid layer was constructed at the film surface. âº The PS/TEOS films exhibited excellent wear resistance and anti-oxidant properties.
