Inspired by nature’s photoprotection mechanisms, we report an effective UV-blocking nanomaterial based on diethyl sinapate-grafted cellulose nanocrystals. This material has been proven very efficient in both cosmetic formulation and PVA films, demosntrating the great potential of such functionnalized nanomaterials.<br/><br/>This presentation of this multidisciplinary research work - which encompasses green chemistry, nanomaterials and physico-chemical properties characterization - will describe (1) the sustainable synthesis of nature-inspired diethyl sinapate (DES), (2) its subsequent grafting on CNC using click-chemistry, (3) the characterization of the resulfing CNC-DES, (4) the use of the latter as UV-blocking material in glycerol- and PVA-based matrices.
