Abstract

Abstract: Polyelectrolyte complexes (PEC) are formed by the electrostatic interaction of ion pairs leading to a wide range of physical properties suitable for various applications, including biomaterials. Salt in PECs leads to plasticization, enhancing their rheology in direct ink writing (DIW) 3D-printing techniques. However, the nonthixotropic flow behavior of PECs necessitates the addition of additives to improve their 3D printability, including fumed silica nanoparticles. We investigated the 3D printing of formulated PECs derived from two strong polyelectrolytes, poly(styrene sulfonate) (PSS), and poly(diallyl dimethylammonium) (PDADMA), via rheological, thermal, and spectroscopic methods, differentiating them from other DIW ink materials.
