Abstract

The present article summarizes an experimental study on the effects of two additives on polypropylene/seaweed (PP/SW) biocomposites by dynamic rheological characterization. Storage and loss moduli as a function of frequency were obtained by small-amplitude shear oscillation tests in parallel-plate mode. Maleic anhydride-grafted polypropylene (MAPP) was found to provide good external lubrication, while CNT masterbatch (CESA) promoted fiber–fiber interaction. Han plot and Cole-Cole plot visibly present the difference between the two interaction mechanisms. A synergistic effect was also observed when MAPP and CESA were simultaneously used in biocomposites. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
