Biocompatible hybrid organic–inorganic sol–gel coatings for corrosion protection of Ti6Al4V alloys

What is it about?

Triethylphosphite (TEP) was used as a phosphorus to modified the properties of organic–inorganic hybrid sol–gel coatings prepared based on mixtures of γ-methacryloxypropyltrimethoxysilane (MAPTMS) and tetramethylorthosilicate (TMOS). Addition of TEP dramatically increased the rate of intermolecular condensation and resulted in materials showing greater cross-linking. Protein (fibrinogen) uptake, osteoblast in vitro biocompatibility and corrosion resistance significantly improved in sol-gel coatings that were modified with the phosphorus precursor TEP
