Nanocomposites consisting of spherical particles of Ag were prepared using a single step in situ method for incorporating metal into PEI whereby the metal is introduced into the dissolved polymer via dissolution as an organometallic complex in the same solvent as the polymer. The kinetic rate of formation of the particles is determined using WAXS and SAX measurements. Nanoparticle formation is found to depend on reducing the solvent/polymer ratio, de-solvating the metal complex. This destabilizes the metal precursor complex, causing it to degrade and the metal particles to phase separate by a thermodynamic, probably spinodal driving force. The size of the nanoparticles varies with the cure temperature and the conditions affecting molecular mobility. [ABSTRACT FROM AUTHOR] |
