DISPERSION OF in situ GRAFTED CARBON BLACK WITH NATURE RUBBER
天然橡胶原位接枝炭黑的分散性研究

In order to improve the dispersibility of carbon black(CB),natural rubber(NR) degraded under high temperature and powerful shear force was grafted onto the CB surface by in situ solid state grafting method.The morphology of original CB and grafted carbon black(GCB) particles was investigated by transmission electron microscope(TEM) and atom force microscope(AFM).The results showed that original CB particles fused together and presented as big dendritic agglomerates whose size was several microns,while the s...
