Direct Extrusion Printability of Internal Phase Nanostructured Hydrogels

An experimental study in open-air direct extrusion of fatty acid-based ternary system gels is presented. When promising self-supporting mechanical abilities are observed in some pure ternary experiments, photoinitiators and hydrogel monomers are introduced to stabilize structures printed from these gels. A systematic approach is conceived and employed to dial in optimal extrusion results, with a demonstration of mechanical aptitude for each studied composition. Evidence of the effects these inclusions have on the ternary gels is observed in the form of SAXS nanostructural analysis, rheological characterization and evaluation, and mechanical tensile load analysis. Comparisons are drawn between these measurements with samples, not including hydrogel monomers and photoinitiators, as well as between compositions containing these materials.
