| Abstract [eng] |
As optical 3D printing technology becomes increasingly popular, along with growing environmental concerns, it is essential to replace synthetic materials with bio-based materials in this technology. Consequently, the objective of this dissertation was to develop acrylated epoxidized soybean oil-based photocross-linked polymers and polymer composites for optical 3D printing technologies. For the first time, this dissertation presents the development of crosslinked acrylated epoxidized soybean oil-based polymers synthesized without any photoinitiator and solvent. Polymeric 3D microstructures were formed by direct laser writing lithography, which were self-sustaining and exhibited a 3D architecture. Acrylated epoxidized soybean oil-based polymers, synthesized from resins containing bio-based comonomers, and acrylated epoxidized soybean oil-based polymer composites with functionalized calcium silicate hydrate fillers synthesized from calcium oxide and silica gel-rich waste material, were successfully applied in digital light processing 3D printing. The photocuring kinetics, thermal, and mechanical properties of polymers were investigated and compared with commercially available synthetic analogs. The developed polymer composites showed improved mechanical and thermal properties compared to those polymers without the filler. Objects produced by digital light processing 3D printing exhibited high printing accuracy, strong adhesion between layers, and a smooth surface finish. The developed bio-based polymers and polymeric composites can be a sustainable and competitive alternative to commercial petroleum-derived polymers in optical 3D printing technology. |
