Resumo

The objective of this work was the characterization of cellulose and cellulose nitrate nanofilms from the mixture of Kraft pulps of  Pinus sp. and Eucalyptus sp. bleached. The production of nanocellulose was made by mechanical processing. To obtain the cellulose nitrate, the nitration was carried out in part of the produced nanocellulose. The characterizations were performed by means of scanning electron microscopy, medium infrared spectroscopy, tensile strength and absorption assay.  The results demonstrate that there was influence of  nitration in the characteristics of the films produced. The nanofilms of cellulose nitrate appear more interesting for the absorption property, indicating the use of this process for uses that require this characteristic.
