The aim of this review was to describe the variety of reactive species derived from biomass that can lead to photosensitive materials through a photopolymerization process, a clean and quick process at room temperature without pollutant emission such as volatile organic compounds (VOC) to make radiation cure coatings. These biosourced macromolecules can be easily modified to obtain photosensitive or UV-reactive macromolecules. The main classes of naturally occurring molecules and macromolecules such as lipids, amino acids (proteins), carbohydrates, polyenes, natural rubber, etc. are detailed. The ways they are extracted, modified, used or integrated in photopolymerizable systems are described in relation to their applications: coatings, biomaterials, biodegradable drug delivery systems, microelectronics or optoelectronics. Different methods such as acrylation by acrylic monomers and thiol-ene coupling are used to modify these renewable feedstock use in materials. The modified renewable materials can be used in various photopolymerization such as radical, cationic, self-initiating, thiol-ene and etc. polymerization. This critical review takes into account the characteristics and reactivity of the various compounds as well as their cytotoxicity, biodegradability and their end uses.
