“…"Contact angle" is explained as the angle formed between a water droplet in contact with a solid substrate [36]. This value is an estimation of hydrophilicity of the substrate [42,43]. This analysis was repeated three times for sample and the average value is reported here as the true contact angle.…”

In this research, functionalization of the easily available polyalphaole n (PAO) based resins is accomplished by the copolymerization of 1-decene with 9-decenol through a facile cationic polymerization route. The resultant Co-oligomer was further functionalized with acryloyl chloride to furnish Macromer product. The exact microstructure of synthesized and modi ed resins was explored via H-NMR, FTIR and GPC analytical methods. The PAO chains contain roughly 20 monomeric units in which three polymerizable C = C moieties could be embedded. The crosslinking of Macromer via visible light irradiation in the presence of a photo-initiator system provided nal fabricate. The effect of photo-initiator content on the cross-linking kinetics of the resin wasexplored using shrinkage strain measurement. The resulted three dimensional PAO (3D-PO) revealed hydrophilic nature with water contact angel of 65° and excellent cell viability of 93% in the MTT assay. This strategy starts from easily available α-ole n based monomers, employs a facile cationic polymerization procedure, enables modulation of the functional groups in the Macromer backbone in order to make it photo-polymerizable, and holds great potential for tissue engineering applications.
