Abstract
Through radio frequency glow discharge the molecular structure of a fluoropolymer is permanently modified by the substitution of hydrogen and oxygen or oxygen-containing radicals for fluorine to a depth of up to 100 .ANG.. The surface morphological properties on a molecular level (e.g., pore structure) of the modified fluoropolymer remain substantially uncharged from those of the starting polymer as well as the bulk structure below the modified surface region while wettability with respect to low surface tension liquids and surface free energy as determined through critical surface tension are increased and new chemically reactive sites are created for further wet chemical modification or attachment of various functionality for development of a bioprobe device.
