Physicochemical Characterization of Portuguese Clay and Nanocomposite Preparation with Polylactide
A Portuguese clay (BRN) from the North East city of Bragança was collected and characterized in terms of health treatment and applied towards the preparation of nanocomposites with Polylactide (PLA). The silt-clay fraction of BRN is mainly composed of smectite with less illite, kaolinite and other m...
