| Resumo: | The objective of this work was to investigate the effect of the addition of a nanocellulose gel from cocoa bean husk (NAC) on nanocellulose gels of Eucalyptus sp. and Pinus sp. The nanogels were obtained by mechanical defibrillation and the films by casting with different concentrations of NAC (0%, 20% and 35%). These were evaluated for morphology, thermogravimetric properties, barrier properties and soil biodegradability. NAC fibres presented the shortest lengths (30–80 µm), and their addition to the films reduced degradation at 350 °C by 17% but did not cause changes in water vapor permeability. NAC increased the solubility and biodegradability of the films, especially those of Eucalyptus sp. (35%). Therefore, the use of NAC proved to be a promising tool in the formulation of biodegradable packaging. |
