Stretching Micro Metal Particles into Uniformly Dispersed and Sized Nanoparticles in Polymer

Abstract There is a longstanding challenge to disperse metal nanoparticles uniformly in bulk polymers for widespread applications. Conventional scale-down techniques often are only able to shrink larger elements (such as microparticles and microfibers) into micro/nano-elements (i.e. nanoparticles an...
