Description

technical field

[0001] The present invention relates to a colloidal solution of metal nanoparticles, a metal-polymer nanocomposite and a preparation method thereof, more particularly, the present invention relates to metal nanoparticles prepared using various polymer stabilizers and having a uniform particle diameter Colloidal solutions and metal-polymer nanocomposites and methods for their preparation. Background technique

[0002] Recently, a method for preparing colloidal dispersions of silver nanoparticles using gamma rays and suitable stabilizers such as polyvinyl alcohol and sodium dodecyl sulfate (SDS) was disclosed (Nature 1985, 317, 344; Materials Letters 1993 , 17, 314). The preparation method using gamma rays is reported to provide silver nanoparticles with uniform diameter distribution. It is known from these famous research reports that the size of metal nanoparticles prepared by those methods is about 8 nm to several tens of nanometers. However, metal nanopa...
