The Development and Characterization of Biodegradable, DLP-Printable, Glycerol-Based Copolymers |
| 초록 |
With the advancement in 3D printing over the past decade, the development of novel 3D printable polymers has been more proporous than ever. In the case of digital light processing additive manufacturing (DLP-AM) systems, the 3D printable materials must be photocurable at near visible light frequency. Considering the radical polymerization nature of photocuring, biodegradability is of these materials are usually of concern. In this work, a novel biodegradable, acrylated polymers, poly(glycerol sebacate) acrylate (PGSA), is developed and copolymerized with polycaprolactone diacrylate (PCLDA) and/or poly(ethylene glycol) diacrylate (PEGDA) to form a network polymer. First, the effect of degree of acrylation in PGSA toward the mechanical and degradation properties is investigated. Second, a series of copolymer with varying weight ratio between the prepolymers is characterized. It is found that by blending prepolymers with various degree of acrylation and at various weight ratios, the viscosity of the prepolymers remains stable, and are even more 3D printable than pure substances. In addition, it is shown that copolymers fabricated by DLP-AM fabrication presents higher mechanical strength than those fabricated via direct UV exposure. The copolymers are then applied to the formation of tissue engineering scaffolds. |
