    • Abstract


      Taking the chitosan (CS) to blend with the tea polyphenols (TP) a CS/TP hydrogel was fabricated. Results showed that this fully green hydrogel has a water content at about 54% and a tensile strength within 10–13 MPa capable for applying to the soft contact lens (SCL) By controlling the added TP percent at 1–2 wt%, this CS/TP hydrogel presented good anti-ultraviolet (UV) property fitting the standards of the class-1 of SCL of US Food and Drug Administration.
