Effect of Treatment Power on Interfacial Properties of Ramie Fiber/Polypropylene (PP)Micro-composites

摘要：

　　In recent years, vegetable fibers are widely used as reinforcements for green composites.One of the major problems in this application is that their hydrophilic surfaces are incompatible with hydrophobic thermoplastic matrices.In order to improve the interfacial properties of ramie fiber/PP composites, ramie fibers were ethanol-pretreated followed by atmospheric pressure plasma jet (APPJ) treatment under different powers.Scanning electron microscopy showed the fiber surfaces of the ethanol-pretreated + APPJ-treated group was rougher than the controlled group.The interfacial shear strength (IFSS) between PP matrix and ramie fiber was increased by 29.77% under the treatment power of 120 W, while the IFSS has no significant improvement when the treatment power is 140 W and 160 W.Moreover, the tensile strength of the single ramie fiber did not exhibit significant decrease for the 120 W plasma treatment.
