Similarly, a number of thiol-ene based elastomers have been developed, making use of the rapid crosslinking of associated residues in air . Hence, an increasing number of reports proposed the crosslinking of polyurethanes, polycarbonates and silicones using thiol-ene coupling, and enabling their application in 3D printing platforms such as filament extrusion and stereolithography, as well as for microfabrication . In addition, thiol-ene and thiol-yne reactive polymers and elastomers allow to confer biofunctionalisation to traditional rigid degradable polymers such as poly(e-caprolactone) (PCL) and poly(lactic acid). For example, propargylated PCL offers attractive functionality via thiolyne coupling or click-azide reactions for the biofunctionalisation of degradable implantable materials for tissue engineering applications .
