Claims30
A composition comprising:
- a UV-curable matrix material, and
- a reinforcing agent having a solubility in UV-curable matrix material that decreases as the UV-curable matrix material is cured,
- wherein the reinforcing agent is present at an amount such that:
- (a) prior to curing the UV-curable matrix material, the reinforcing agent is at least partially dissolved in the UV-curable matrix material, and
- (b) upon curing the UV-curable matrix material, at least a portion of the reinforcing agent is precipitated, thereby forming a phase-separate domain in the cured UV-curable matrix material.

A composition comprising:
- a UV-curable matrix material, and
- polyvinylpyrrolidone or poly(methyl methacrylate), wherein the polyvinylpyrrolidone or poly(methyl methacrylate) is present at an amount such that:
- (a) prior to curing the UV-curable matrix material, the polyvinylpyrrolidone or poly(methyl methacrylate) is at least partially dissolved in the UV-curable matrix material, and
- (b) upon curing the UV-curable matrix material, at least a portion of the polyvinylpyrrolidone or poly(methyl methacrylate) is precipitated, thereby forming a phase-separate domain in the cured UV-curable matrix material.

A composition comprising:
- a UV-curable matrix material which, upon curing, forms a cured UV-curable matrix material comprising a polymer comprising acrylate, thiol-ene, or the combination thereof, and
- a reinforcing agent having a solubility in UV-curable matrix material that decreases as the UV-curable matrix material is cured,
- wherein the reinforcing agent is present at an amount such that:
- (a) prior to curing the UV-curable matrix material, the reinforcing agent is at least partially dissolved in the UV-curable matrix material, and
- (b) upon curing the UV-curable matrix material, at least a portion of the reinforcing agent is precipitated, thereby forming a phase-separate domain in the cured UV-curable matrix material.
2 more elements
A composition comprising:
- a UV-curable matrix material which, upon curing, forms a cured UV-curable matrix material comprising a polymer comprising acrylate, thiol-ene, or the combination thereof, and
- polyvinylpyrrolidone or poly(methyl methacrylate), wherein the polyvinylpyrrolidone or poly(methyl methacrylate) is present at an amount such that:
- (a) prior to curing the UV-curable matrix material, the polyvinylpyrrolidone or poly(methyl methacrylate) is at least partially dissolved in the UV-curable matrix material, and
- (b) upon curing the UV-curable matrix material, at least a portion of the polyvinylpyrrolidone or poly(methyl methacrylate) is precipitated, thereby forming a phase-separate domain in the cured UV-curable matrix material.
