Abstract
The use of composite materials are increasing in industries and it has been shown that the use of nanocomposites in the field of Tissue Engineering can increase compatibility between cells and polymer matrix material, as well as promote tissue regeneration and inhibit the formation of fibroses. In this work, we report on the production of poly(vinyl alcohol) (PVA) nanocomposite, with nanocellulose or carbon nanotube (CNT), aiming at its use as a biomaterial in scaffolds. The composite powders were produced by spray drying. Their morphologies were verified with a scanning electron microscope and their crystallinity analysed by X-ray diffractometry. The particles obtained by this method are not rigid, although the shapes are spherical-like. Although the powder was obtained, it appears that the polymer undergoes degradation, probably due to the high temperature used for its preparation.
