Research on Polypropylene reinforced with Rice Straw micro/nano Fibrils Nanocomposite

摘要：

The rice straw (Oryza sativa L.) pulp was treated by high intensity ultrasonication to make fibrils. The rice straw fibril (RSF) was used as reinforcement of RSF/polypropylene (PP) nanocomposite. The influences of RSF and coupling agent (MAPP) contents on tensile properties of nanocomposite were tested. The results showed: RSF loading was 5％, the tensile strength up to the maximum value of 31.71 GPa. With increasing fibril loading the tensile modulus increased first then decreased. However, the elongation at break decreased with increasing fibril loading. There was no significant influence of MAPP content on tensile strength and elongation at break of PP and RSF/PP nanocomposite. When MAPP content was 4％, the tensile modulus of PP and RSF/PP nanocomposite all appeared maximum values.
