title: Stabilization of photochromic isomers by copper nanoparticles in a high-diffusivity solid matrix.
abstract: Nanoparticles that are dispersed in a solid matrix have no effect on co-dispersed molecules unless they happen to be located close to one another. A polymer with a high diffusion coefficient allows molecules to circulate in the matrix to find a particle that enhances their function. A polymer composite containing copper nanoparticles was created by a low-temperature, nonvacuum process. That is, laser ablation was conducted in polydimethylsiloxane oil for both anti-oxidation and efficient particle collection, and then this suspension was cured to create a metal-polymer composite. This composite enhanced optical functions of a photochromic dye owing to its high diffusivity.
