Calcium Phosphate Coatings by Sol-Gel on Acrylonitrile-butadiene-styrene Substrate

Additive manufacture is an effective technology to produce complex macrostructures from polymers. Sol-gel is a chemical process that affords multifunctional materials by functionalization of different substrates. This work reports on the use of acrylonitrile-butadiene-styrene polymer (ABS) as starting material to obtain a substrate by additive manufacture. Coating of ABS by the sol-gel methodology generated a multifunctional material. Sols with and without phosphate ions were prepared from silicon and calcium alkoxide. Based on X-ray diffraction patterns, a calcium phosphate crystalline struct...
