Abstract

Compositions and methods for changing a property of a coating are provided. The coating includes a dynamic material configured to be reversibly convertible between a hydrophobic state and a hydrophilic state, wherein transition between the hydrophilic state to the hydrophobic state occurs in an environment dependent manner. The coating also includes an environment altering material configured to alter the hydrophobic or hydrophilic state of the dynamic material.

First claim

What is claimed is:

1. A composition to coat a surface, the composition comprising:
at least one dynamic material, wherein the at least one dynamic material is configured to be reversibly convertible between a hydrophobic state and a hydrophilic state, wherein transition between the hydrophilic state and the hydrophobic state occurs in a heat dependent manner, and wherein the at least one dynamic material comprises at least one thermosensitive block copolymer that comprises (2-ethoxy)ethoxyethyl vinyl ether (EOEOVE) and octadecyl vinyl ether (ODVE); and
at least one heat generating material, wherein the at least one heat generating material is configured to absorb an amount of energy and to convert at least some of the amount of energy to heat.

2. The composition of claim 1 , further comprising at least one resin.

3. The composition of claim 2 , wherein the at least one dynamic material and the at least one heat generating material are different materials from the at least one resin.

4. The composition of claim 1 , wherein the at least one heat generating material comprises at least one nanoparticle.

5. The composition of claim 4 , wherein the at least one heat generating material is configured to absorb at least one of infrared energy, microwave energy, or ultrasonic energy.

6. The composition of claim 4 , wherein the at least one nanoparticle comprises at least one of a core-shell nanoparticle, an aggregated nanoparticle, a multi-layered nanoparticle, a magnetic nanoparticle, or a hollow nanoparticle.

7. The composition of claim 1 , wherein the at least one heat generating material comprises at least one of an Au core-shell nanoparticle, a Fe 3 O 4 nanoparticle, a CoFe 2 nanoparticle, a Ni—Cu nanoparticle, a Fe—Pt nanoparticle, a Pd—Co nanoparticle, a PLGA microbubble nanoparticle, or a PVA microbubble nanoparticle.

8. A composition to coat a surface, the composition comprising:
at least one dynamic material, wherein the at least one dynamic material is configured to be reversibly convertible between a hydrophobic state and a hydrophilic state, wherein transition between the hydrophilic state and the hydrophobic state occurs in a heat dependent manner, and wherein the at least one dynamic material comprises (2-ethoxy)ethoxyethyl vinyl ether (EOEOVE) and octadecyl vinyl ether (ODVE);
at least one heat generating material, wherein the at least one heat generating material is configured to absorb an amount of energy and to convert at least some of the amount of energy to heat, and wherein the at least one heat generating material comprises at least one of an Au core-shell nanoparticle or a PLGA microbubble nanoparticle; and
at least one resin, wherein the at least one resin comprises at least one of a polyurethane resin or an acrylic resin.

9. The composition of claim 8 , wherein the at least one heat generating material is configured to absorb at least one of infrared energy, microwave energy, or ultrasonic energy.
