The vulcanized NR film was prepared with mixing of natural rubber latex(NRL) with various additives by dipping process. It was investigated optimum condition of the mature time, swelling degree, cure time at 110℃, and measured the mechanical properties of tensile stength and elongation. Hydrogel coated NR films were prepared by dipping poly(AA-co-HEMA) solution upper the surface of one dipped NR film of its condition. In order to identify the surface structure and the slip properties of hydrogel coated NR films, contact angles and static·kinetic friction coefficient were measured. Contact angles were increased with increment of poly(AA) mole ratio of poly(AA-co-HEMA), and static·kinetic friction coefficient were increased rapidly for the hydrogel coated NR films than for the NR films. From the results, hydrogel coated NR films has slip`s reinforcement in skin contact surface with increased of blend ratio of poly(AA-co-HEMA) solution.
