This study investigates how atmospheric twitch plasma jet (APPJ) treatment with fermentation alcohol pretreatment whitethorn improve ramee fiber surface properties for better love to polypropylene. After soaking in grain alcohol for 10 min, ramie fibers are treated by atomic number 2 plasma. Scanning electron microscopy shows append fiber surface impertinence due to plasma etching, which favors mechanized interlocking of the interface. X-ray photoelectron spectroscopy analysis indicates increased deoxycytidine monophosphate contents and hydrophobic C-C bonds. large advancing water hit angles are found in dynamic water affair angle measurement.

Microbond test shows a nearly 50% increase of the interfacial overcharge expertness of the fibers to polypropylene compared to the control, which may be attributed largely to the reaction of ethanol molecules and cellulose in plasma treatment, leading(a) to increased hydrophobicity in the ramie fibers and thus improving their compatibility to polypropylene matrix.

Introduction Cellulose natural fibers have been insurrection as low cost, widely available, renewable, and environmentally friendly substitutes to non-renewable manmade fibers much(prenominal) as glass and synthetic fibers in composites [1-3]. Thermoplastic composites built with natural fibers are enjoying...If you want to circumvent a integral essay, roll it on our website: Ordercustompaper.com
