在温和的条件下，利用双功能分子调节纳米颗粒的生长，结合原位生成SO4 -，实现了可控的表面功能化BaSO4纳米颗粒的原位合成。这种表面带有乙烯基的BaSO4纳米颗粒比传统的BaSO4颗粒更能增强PMMA骨水泥。
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.
