abstract = "In Brazil, banana cultivation (Musa sapientum) generates large
amounts of waste consisting of cellulose, hemicellulose and
lignin. Lignocellulosic fibres have important features such as
biodegradability, low toxicity, non-abrasive, low density and good
specific mechanical properties, justifying their potential as
substitute for synthetic fibres in applications, such as
reinforcement in polymeric composite. However, the presence of
hydroxyl group and low thermal stability of natural fibres may
limit their use for this application. Some authors report the use
of chemical and physical treatments in the fibres to improve the
adhesion to the matrix. From the chemical treatment of banana
fibres with a mixture of acetic and nitric acids it was possible
to isolate the semicrystalline cellulose. This study aims to use
isolated pulp of banana fibres like organic matrix of a fibrous
hybrid material containing hydrous magnesium oxide in mass
proportions equal to 2% and 3%. The generated hybrids were
characterized by X-ray diffraction (XRD), thermogravimetric
analysis (TGA) and Fourier Transform Infrared Spectroscopy (FTIR).
TGA curves show that thermal degradation of main fraction of
material occurred at higher temperatures. XRD curves indicate that
the hybrids have different characteristics from their precursor.
FTIR analyzes show that the chemical treatment with acetic acid
induced partial acetylation of banana fibre.",
