The main goal of this work was the development of photoactive multilayer films. Taking into account that chitosan is a biodegradable, biocompatible, nontoxic, and antibacterial biopolymer, the fabrication of chitosanbased multilayer films can be an interesting pathway to obtain biopolymer-based films in which properties can be combined with a light-responsive material, such as an azobenzene-containing polymer. In particular, the layer-by-layer technique was used for the fabrication of the optically active films consisting of alternating layers of chitosan and an azopolymer. The influence of the pH and the number of bilayers on the structure and properties of the films was investigated by different experimental techniques and it was found that the roughness and elastic modulus of the multilayer films increased with the decrease in chitosan solution pH. Besides, induced birefringence measurements revealed that a higher level of photoorientation was attained with the decrease in pH and the increase in bilayer number of the developed films.

More about this publication?
  • The Journal of Renewable Materials (JRM) publishes high quality peer reviewed original research on macromolecules and additives obtained from renewable/biobased resources. Utilizing a multidisciplinary approach, JRM introduces cutting-edge research on biobased monomers, polymers, additives (both organic and inorganic), their blends and composites. It showcases both fundamental aspects and new applications for renewable materials. The fundamental theories and topics pertain to chemistry of biobased monomers, macromoners and polymers, their structure-property relationship, processing using sustainable methods, characterization (spectroscopic, morphological, thermal, mechanical, and rheological), bio and environmental degradation, and life cycle analysis. Demonstration of use of renewable materials and composites in applications including adhesives, bio and environmentally degradable structures, biomedicine, construction, electrical & electronics, mechanical, mendable and self-healing systems, optics, packaging, recycling, shape-memory, and stimulus responsive systems will be presented.
