Claims44
A method for making a structure, comprising:
- (a) applying a multiphoton-curable composition to a molded article, wherein the composition comprises a curable species and a multiphoton photoinitiator system;
- (b) at least partially curing the multiphoton-curable composition to form a structure on the article.
A method of adding a structure to an article, wherein the article has a surface with at least one microscopic feature, the method comprising:
- (a) applying a multiphoton-curable composition to the feature, wherein the composition comprises:
- (1) a curable species, and
- (2) a multiphoton photoinitiator system comprising a multiphoton photosensitizer and an electron acceptor;
- (b) at least partially curing the multiphoton-curable composition to form a structure.
A method of adding a structure to an optical fiber, the method comprising:
- (a) applying a multiphoton-curable composition to the optical fiber, wherein the composition comprises:
- (1) a curable species, and
- (2) a multiphoton photoinitiator system comprising a multiphoton photosensitizer and an electron acceptor;
- (b) at least partially curing the multiphoton-curable composition to form a structure.
