Polyaniline and magnetite on curaua fibers for molecular interface improvement with a cement matrix

Modifications were used in the natural fibers, aiming for a more outstanding adhesion between vegetable fibers and cement-based matrices. As a reinforcement load, improvements in dimensional stability (due to high hydrophilicity) and compatibility between both phases are necessary. In this work, reinforcement fibers were developed from hornified curaua fibers (HF) modified with polyaniline (HF-PAni), magnetite (HF-Mag), and both (HF-PAni/Mag)....
