Calcium phosphate/microgel composites for 3D powderbed printing of ceramic materials
Abstract
<jats:title>Abstract</jats:title> <jats:p>Composites of microgels and calcium phosphates are promising as drug delivery systems and basic components for bone substitute implants. In this study, we synthesized novel composite materials consisting of pure <jats:italic>β</jats:italic>-tricalcium phosphate and stimuli-responsive poly(<jats:italic>N</jats:italic>-vinylcaprolactam-co-acetoacetoxyethyl methacrylate-co-vinylimidazole) microgels. The chemical composition, thermal properties and morphology for obtained composites were extensively characterized by Fourier transform infrared, X-ray photoelectron spectroscopy, IGAsorp moisture sorption analyzer, thermogravimetric analysis, granulometric analysis, ESEM, energy dispersive X-ray spectroscopy and TEM. Mechanical properties of the composites were evaluated by ball-on-three-balls test to determine the biaxial strength. Furthermore, initial 3D powderbed-based printing tests were conducted with spray-dried composites and diluted 2-propanol as a binder to evaluate a new binding concept for <jats:italic>β</jats:italic>-tricalcium phosphate-based granulates. The printed ceramic bodies were characterized before and after a sintering step by ESEM. The hypothesis that the microgels act as polymer adhesive agents by efficient chemical interactions with the <jats:italic>β</jats:italic>-tricalcium phosphate particles was confirmed. The obtained composites can be used for the development of new scaffolds.</jats:p>
