    Abstract: There is disclosed a method of raising the surface energy of a fluoropolymer to enable one to wet the surface thereby allowing adhesion of various materials to the surface. The method involves placing the fluoropolymer in a sealed chamber while introducing a combination of oxygen and ammonia gas into the chamber at a predetermined pressure range and at a selected rate. A plasma is created in the chamber during the introduction of the gases for an interval sufficient to remove a substantial amount of fluorine from the surface of said fluoropolymer thereby raising the surface energy of the same.

    Abstract: A method for forming plastic packaging products (containers, tanks, etc.) that have a surface which has been subjected to a reactive gas atmosphere containing F2, Cl2, O2, O3, or SO3, oxidative acids, or mixtures thereof, at a temperature and gas partial pressure sufficient to increase the surface energy to at least 40 dynes/cm in order to provide adhesion of the barrier coating, or molding the container in plastic resin that was first surface modified by one of the preceding processes and molded under conditions such that a surface is developed on the container that has a minimum of 40 dynes/cm and which will adhere well to coatings. A barrier coating is then applied. The barrier coating may be of various polymers and blends, all meeting the critical requirements that the coating must adhere tenaciously to the surface, must have good barrier properties for the molecules which are to be contained, and must not diminish the impact resistance of the material to which it is applied.

The biofunctional material substrate retains bioactivity in the admixture. As disclosed, the compositions may be made by a process which comprises contacting a mixture of the substrates or their precursors with a supercritical fluid under supercritical conditions of reduced viscosity to plasticise and swell the biofunctional polymer substrate and under conditions of physical blending to distribute the biofunctional material substrate throughout the biofunctional polymer substrate, and releasing the supercritical fluid under subcritical conditions. Also disclosed are biofunctional polymer matrices and methods of making and using thereof.
