Abstract
Disclosed is a method for mechanically anchoring polymers on the surface of a porous substrate by trapping polymer chains within the pores of the substrate under capillary forces. Surface modification of the porous substrate is achieved by anchoring one end of the polymer chains within the pores while one or more other ends of the polymer chains dangle from the surface of the porous substrate. The method provides a unique way of modifying the surface of a material without chemical reactions or precursor-substrate interactions.
