This research aimed to apply the Blown Film Extrusion technique to synthesize the titanium dioxide (TiO2) bio-composite films incorporated on a thin film as a photocatalyst. The biopolymer materials have great recognition via their renewable and biodegradable characteristic and the green composite has been a new challenge path to replace traditional polymer composite. In this work, TiO2/Polybutylene succinate (PBS) bio-composite film was developed to be used as a supporter for determining the photocatalytic oxidation activity of the TiO2 on the chlorinated volatile organic compounds degradatio

Abstract:
Lignin fractions having different molecular weights and varied chemical structures isolated from kraft lignins of both softwood and hardwood via a sequential solvent fractionation technique were incorporated into a tunicate cellulose nanofibers (CNF)—starch mixture to prepare 100% bio-based composite films. The aim was to investigate the impact of lignin structural diversity on film performance. It was confirmed that lignin’s distribution in the films was dependent on the polarity of solvents used for fractionation (acetone > methanol > ethanol > ethyl acetate) and influenced the opti

Abstract:
Bio-based composite films have been widely studied as potential substitutes for conventional plastics in food packaging. The aim of this study was to develop multifunctional composite films by introducing cellulose nanofibers (CNF) and lignin into starch-based films. Instead of costly and complicated chemical modification or covalent coupling, this study optimized the performance of the composite films by simply tuning the formulation. We found that starch films were mechanically reinforced by CNF, with lignin dispersing as nanoparticles embedded in the matrix. The newly built-up hydrogen bond

The environmental problems generated by pollution due to polymers of petrochemical origin have led to the search for eco-friendly alternatives such as the development of biopolymers or bio-based polymers. The aim of this work was to evaluate the electrochemical behavior of a biopolymer composite made from cassava starch and cardol extracted from cashew nut shell liquid. The biopolymers were prepared using the thermochemical method, varying the synthesis pH and the cardol amounts.

In this study, chitosan-based composite films blended with a dextran like exopolysaccharide derived from lactic acid bacteria were prepared using the solvent casting method. Later, these composite films were plasticized with 1,3-propanediol (1,3-PDO) produced biologically using biodiesel derived crude glycerol. Further, their physical properties, such as tensile strength, water vapor barrier, thermal behavior, and antioxidant properties, were tested. In comparison to the control chitosan-exopolysaccharide films, 1,3-PDO plasticized films increased tensile strengths (20.08 vs. 43.33 MPa) with a
