Claim:
1. A method for forming a wettable inorganic-organic hybrid coating on the surface of a polycarbonate construct to improve the lubricity of the surface of the polycarbonate construct, comprising: activating the surface of a polycarbonate construct by placing the construct in an activation solution and heating the solution at a selected activation temperature for a selected activation time; drying the activated construct; coating the activated construct by immersing the construct in a coating solution and heating the solution at a selected coating temperature for a selected coating time to form an inorganic hybrid coating on the surface of the construct; drying the coated construct; and quenching the coated construct by immersing the coated construct in a quenching solution contained within an autoclavable vessel and autoclaving the coated construct for a selected autoclaving time at a selected autoclaving temperature, the surface of the quenched coated construct having increased wettability and a decreased coefficient of friction compared to the wettability and coefficient of friction of an uncoated surface of a polycarbonate construct.
