Introduction.Aerogel composed of a polymer/clay dispersion is material with great potential for application in several areas. This unique structure gives it properties, low density, very high porosity,and remarkable thermal resistance, making ideal applications ranging from insulation to air pollutant absorption. Objective. work aimed review the main parameters that influence improvement mechanical properties aerogels over last ten years. Methodology.The research was conducted December2023...
Tree-exuded gums are natural polymers that represent an abundant raw material in the food and pharmaceutical industries. The cashew gum can be obtained by exudation of trees genus Anacardium, a native species Brazilian northeast; its polymer consists monosaccharide units propitious to action chemical reactions tend improve their intrinsic characteristics among them, as degree hydro-solubility. objective this work was modify exudate Anacardium occidentale (cashew (CG)) through amine reaction....
The incorporation of polymeric components into aerogels based on clay produces a significant improvement in the physical and thermal properties aerogels. In this study, clay-based were produced from ball by angico gum sodium alginate using simple, ecologically acceptable mixing method freeze-drying. compression test showed low density spongy material. addition, both compressive strength Young's modulus elasticity progression associated to decrease pH. microstructural characteristics...
