The problems caused by synthetic plastics have motivated the use of other materials. This research consisted of taking advantage of the banana peel and cellulose from the pseudostem of this plant to obtain a bioplastic. Dry milling was applied to extract the flour and an acid-alkaline treatment for the cellulose. The elaboration of the thermoplastic material did with a mixture design where fixed amounts of shell flour (5 g), 15% NaOH (5 mL), and water (4 mL), varying the concentrations of the plasticizers, which were glycerol and sorbitol. In two of the formulations, was added as filler 0,5 g of cellulose. The bioplastic obtained was characterized according to its thickness, water vapor permeability (WVP), tension force (TF), break time (bt), and biodegradability. The type of plasticizer and the cellulose content did not affect the thickness of the bioplastic, but it did affect the WVP, TF, and bt. WVP decreases when glycerin is used and increases with the addition of cellulose. The best result for WVP was 1,83 x 10-9 g/Pa.s.m in the formulation where only was used glycerol, while the best values for TF, bt, and biodegradability were 2,4 MPa, 17 seconds, and 37,77%, respectively, with 75% sorbitol and 25% glycerol. Expanding the study of the best formulations would allow their use as a replacement for synthetic plastics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
