Abstract
Methods of forming nanocomposites comprising a polymer and metal nanoparticles are disclosed. The nanoparticles are disposed within a matrix of the polymer. In particular, the nanoparticles are formed in situ in an extruder. The methods comprise providing a reaction mixture comprising a polymer, a metal precursor, and a solvent and extruding the reaction mixture to form a polymer nanocomposite. The methods overcome nanoparticle dispersion issues arising from melt blending processes.
