Abstract
In recent years, Poly(ethylene)-glycol-diacrylate (PEGDA) has been widely implemented in many biomedical applications such as tissue engineering. Additionally, hydrogels are described as gelatinous substances that can be strengthened mechanically by incorporating suitable fillers. For this research project, the mechanical characteristics of a PEGDA-cellulose nanocrystal hybrid hydrogel, manufactured by UV-DLP printing, will be studied. PEGDA can be mixed with cellulose nanocrystal to be crosslinked by means of UV light exposure, yielding a solid structure. This mixture will be developed in different concentrations and printed in a Cellink LUMEN X Printer to observe the changes in mechanical properties. Quasi-static mechanical tests (tensile and compression) and dynamic mechanical testing (3point-bending and tensile) will be performed to evaluate the mechanical performance of the hybrid hydrogels. In addition, swelling ratio and light absorbance of PEGDA-Cellulose hybrid hydrogels across the ultraviolet and visible ranges of electromagnetic spectrum will be measured as well. Results could help further steps toward using a proper concentration of cellulose to achieve optimum mechanical properties suitable for tissue engineering applications.
