A review of trends in the development of bionanocomposites from lignocellulosic and polyacids biomolecules as packing material making alternative: A bibliometric analysis

Contamination caused by the accumulation of petrochemical-based plastics has reached worrying magnitudes and led to the development of biopolymers as an option to mitigate the problem. This work thus presents a bibliometric analysis of all that concerns the development of such bionanocomposite materials, using ScientoPy and SciMAT software to establish associations between the number of published documents, countries, in-stitutions and most relevant topics. The bionanocomposites topic was found to throw up the biggest number of documents associated (2008) with the different types of raw materials and methods used to obtain nanoparticles and their combination with biopolymeric materials, the result known as a bionancomposite*. Analysis of the documents related to the application for development of packaging materials from biological molecules, car-bohydrate polymers, compounds, conjugates, gels, glucans, hydrogels, membranes, mucilage (source unspeci-fied), mucoadhesives, paper, polymers, polysaccharide, saccharides etc, is also presented, emphasizing mechanical, thermal and barrier properties, which, due to the inclusion of nanoparticles mainly from natural sources of cellulose, show increases of up to 30%. The inclusion of nanoparticles, especially those derived from cellulose sources, generally seeks to increase the properties of bionanocomposite materials. Regarding an in-crease in mechanical properties, specifically tensile strength, inclusions at percentages not exceeding 10 wt% can register increases that exceed 30% were reported.

Automated summary

The development of biopolymers as an option to mitigate pollution caused by the accumulation of petrochemical-based plastics has led to a focus on bionanocomposite materials. These materials show enhancements in mechanical, thermal, and barrier properties by incorporating nanoparticles, particularly from natural sources like cellulose. The analysis also highlights the significant increase in tensile strength, exceeding 30%, with inclusions of nanoparticles not exceeding 10 wt%.
