Characterization of chemically treated jute fiber reinforced polyethylene clay nanocomposites as a function of treatment methods

The hydrophilic nature of natural fibers unfavorably affects adhesion with a hydrophobic matrix which cause loss of strength. In order to reduce hydrophilicity and remove non cellulosic constituents to enhance the interfacial interaction with the polymer matrices, the jute fibers (Corchorus olitoriu...
