Color-adjustable contact lens material and preparation method thereof |
| abstract |
The invention discloses a color-adjustable contact lens material and a preparation method thereof. The material comprises color ink containing two-dimensional van der Waals heterojunction and hydrogel which are mixed to prepare the material; the two-dimensional Van der Waals heterojunction is composed of two-dimensional MOFs nanosheets Zn (NCS) 2 (C 4 N 2 H 4 ) 2 ) And two-dimensional MOFs Nanosheet Co (NCS) 2 (C 4 N 2 H 4 ) 2 Mixing the components; the hydrogel is copolymer hydrogel prepared from methacrylic acid-2-hydroxyethyl ester monomer. The color-adjustable contact lens prepared by the invention does not contain any chemical pigment, and shows excellent biological safety and wearing comfort in wearable application. |
