Abstract
A three-dimensional structure of monodispersed particles, wherein the particles are formed from an emulsion polymerization comprising both hydrophobic and hydrophilic monomers.
Claims31
A polymeric particle formed by an emulsion polymerization of one or more hydrophobic monomer, one or more hydrophilic monomer, and one or more cross-linker;
- wherein at least one hydrophobic monomer and at least one hydrophilic monomer are mixed prior to initiation of polymerization.
A method of making a polymeric particle, comprising the steps of:
- a) mixing one or more hydrophobic monomer, one or more hydrophilic monomer, and one or more cross-linker, in a solvent;
- and
- b) initiating an emulsion polymerization.
A method for making an opal latex, where the three-dimensional periodic structure of the polymeric particles in the opal latex reproducibly has the same opalescent color.
A polymeric particle formed by an emulsion polymerization that reproducibly results in a particle size from about 200 nm to about 290 nm, where multiple particles form a three-dimensional periodic structure with a blue green opalescent color.
A polymeric particle formed by an emulsion polymerization that reproducibly results in a particle size from about 400 nm to about 580 nm, where multiple particles form a three-dimensional periodic structure with a violet opalescent color.
