Effect of corona discharge on the wettability and geometric surface structure of polylactide
Surface layer of corn. polylactide (PLA) was modified with corona discharges and studied for contact angle (H(2)O, CH(2)J(2)) and the geometric structure (at. force microscopy). The surface free energy was calcd. by using Owens-Wendt equation. The treatment resulted in a decrease in the contact angle and an increase in the surface free energy of the PLA film.
