Abstract
Surface energy gradient surfaces with changes in the ratio of the polar component ( γ s p ) to the dispersive component ( γ s d ) of the surface energy γ s have been successfully fabricated by irradiating CR-39 solid-state nuclear track detectors (SSNTDs) with 3 MeV alpha particles with different fluence followed by irradiation with ultraviolet photons with 257 nm. The alpha-particle source has an activity of 0.1 μ Ci and the irradiation time ranges from 1 to 7 d. The contact angles for doubly distilled water, glycerin and ethylene glycol, as well as γ s do not vary significantly with the alpha-particle irradiation. In contrast, γ s p decreases steadily while γ s d increases steadily, and the ratio γ s p / γ s d decreases significantly with the alpha-particle fluence. Such surface energy gradient surfaces are of particular interest for establishing the relationship between the γ s p / γ s d ratio and the biocompatibility.
