Halloysite Nanotubes/Natural Rubber (Hnts/Nr) Nanocomposites: Preparation And Properties

This research focused on the effect of various HNTs loading on the properties of natural rubber nanocomposites. Series (1), HNTs filled in two types of natural rubber i.e., unmodified and modified natural rubber namely SMR L and ENR 50 respectively were investigated. In Series (2), the study of part...
