Abstract
In this research, a collagen-reinforced bio-composite from tung oil was prepared using free radical initiation and thermal polymerization, leading to polyolefinic tung oil-based matrix. Two peptides (long and short) were synthesized and their secondary features were analyzed using circular dichroism spectroscopy. After this analysis, the long peptide exhibited more triple helix characteristics as compared to the short peptide. The full protein will ultimately have a better interaction with the tung oil, was used in the synthesis of the collagen-reinforced bio-composite. The presence of NaCl in the triple helix and its overall effect on the thermal and mechanical properties of the bio-composite was also investigated. Cure time was determined through differential scanning calorimetry (DSC). The thermo-mechanical properties were assessed by means of thermogravimetric analysis (TGA) and dynamic mechanical analysis (DMA), showing impressive improvement in storage modulus upon addition of the triple helix long peptides.
