The use of nonrenewable petroleum-based materials is a significant environmental concern in today’s world due to their persistent nature and toxic effects. Developing alternative products to replace petrochemicals is becoming increasingly important. As a result, there has been an increasing trend toward materials with bio-content in recent years. Citral, which is found in several plants in high abundance, is known to undergo photodegradation and photo rearrangements. Therefore, the photopolymerization of citral is challenging. In this work, we report the successful polymerization of citral and the preparation of photosets via thiol-ene photopolymerization. We solved this challenge by utilizing a two-step polymerization procedure. First, we added triethylamine (TEA) to the formulations to induce thiol-Michael addition reactions. In the second stage, networks are formed via radical-induced thiol-ene photopolymerization. Moreover, citral was blended with limonene to improve the mechanical properties. The networks displayed gel content values in the range of 84%–97%. The water absorption values were found to be less than 3.0%. All photosets were found to be optically transparent in the visible region. Moreover, the results revealed that the networks have very high antioxidant activities and non-leaching contact-killing anti-bacterial properties. Finally, limonene-free photosets were found to be fully degradable under alkaline conditions.
