Serial title, monograph or event: | Molecules | Volume: | 28 | Issue: | 5 | Abstract: | Herein we describe the design of natural curcumin ester and ether derivatives and their application as potential bioplasticizers, to prepare photosensitive phthalate-free PVC-based materials. The preparation of PVC-based films incorporating several loadings of newly synthesized curcumin derivatives along with their standard solid-state characterization is also described. Remarkably, the plasticizing effect of the curcumin derivatives in the PVC material was found to be similar to that observed in previous PVC-phthalate materials. Finally, studies applying these new materials in the photoinactivation of S. aureus planktonic cultures revealed a strong structure/activity correlation, with the photosensitive materials reaching up to 6 log CFU reduction at low irradiation intensities. | URI: | https://hdl.handle.net/10316/113866 | ISSN: | 1420-3049 | DOI: | 10.3390/molecules28052209 | Rights: | openAccess |
