The density (𝜌 𝑐 ) of the nanocomposites was calculated using the Archimedes principle. The nanocomposites were immersed in distilled water on a Sartorius YDK03 hydrostatic balance, and the buoyancy (𝐺) determined using 𝐺 = 𝑊 𝑎 -𝑊 𝑓𝑙 where 𝑊 is the weight of the nanocomposite in air (𝑎) and water (𝑓𝑙) respectively. The temperature of the water was measured using a thermometer and the density calculated using:
