Abstract:
Controlled in situ synthesis of surface functionalized BaSO4 nanoparticles is achieved by using a difunctional molecule to modulate the growth of nanoparticles coupled with in situ generation of SO4 2- under mild conditions. Such BaSO4 nanoparticles with surface vinyl groups reinforce the PMMA bone cement better than conventional BaSO4 particles.
