Naturally Derived Biocompatible Photoinitiators for 3D Printing
type: CreativeWork
description: Photopolymerization is a technology that fulfills the requirements of instant production. Recently. considerable biocompatible materials have been involved in photopolymerization-based manufacturing. To achieve this, photoinitiator is a crucial component. Commercial photoinitiators, are synthetic and eco-unfriendly, causing potential health concerns due to their migration effect. Therefore, natural photoinitiators have drawn tremendous research interest due to their known bioactivities and nature-derived origin. In this regard, this thesis mainly concentrates on 1) the development of naturally occurring photoinitiators demonstrating excellent photoinitiation abilities, 2) the formulation of the investigated photoinitiators involved conventional commercial resins (i.e., dental resin and epoxy) or 3D resins for shape memory hydrogels. In the present thesis, four natural plant extracts are investigated as photoinitiator candidates, extracted from berries, citrus, pomegranate, and Indigofera, respectively. Moreover, the innovative designed functional materials have been successfully 3D printed. Chapter 1 introduces the recent reported naturally derived photoinitiators. Chapter 2 investigates berries-extracted flavones, morin and quercetin, as photoinitiators. Both morin and quercetin exhibit visible light sensitivity and demonstrate their photoinitiation abilities under the irradiation of visible light. Meanwhile, their photoinitiation ability differences are observed in all kinds of photopolymerizations. Chapter 3 introduces citrus-extracted naringin as a water-soluble natural photoinitiator. Naringin demonstrates its excellent visible light absorption in alkali environments and rapid photoreaction with the addition of a coinitiator upon exposure to visible light. Subsequently, a high-fidelity 3D printing is achieved. Meanwhile, the degree of alkaline manipulates the degree of crosslinking. Moreover, an additional monomer, sodium acrylate is introduced to endow the res…
