Abstract

In this study, the effect of using maleic anhydride and oxidizer (dicumyl peroxide) in improving the properties of composites made of polypropylene and cellulose nanocrystal was investigated. Then, the mechanical, and morphological properties of these composite products were explored. Tensile strength increased with increasing cellulose nanocrystal, but it decreased slightly while 5% of cellulose nanocrystal were added. Due to the addition of maleic anhydride and oxidizer, the mechanical properties of the composite product were reduced which was not expected. Analysis of the contact angle of the samples also showed a decrease in wettability behavior due to increased use of nanocrystalline cellulose as well as maleic anhydride and dicumyl peroxide.
