Surface Functionalization of Ta_2O_5/SiO_2 for Filier/Polymer Composites in Dental Applications

摘要

Composites containing nanoparticles which are,e.g.,used as dental fillings,have to exhibit superior properties compared to unfilled poly-mers.Particles do typically not form any che-mical bonds to the polymeric matrix during the polymerization process [1],so that the par-ticles act as voids in the polymeric matrix on mechanical Stresses [2],thereby,reducing the mechanical strength of the composite [3].
