Study on damping and mechanical properties of nano-titanium dioxide/acrylonitrile butadiene-rubber hollow fiber

摘要

TiO2/NBR-PVC hollow fibers were spinned by NBR casting solution blended PVC with nano-titanium dioxide (TiO2). The effect of NBR-PVC hollow fiber damping and mechanical properties aroused by loading TiO2 were studied. Results showed that the hollow fibers loaded TiO2 increased in tensile strength, storage modulus, stiffness and glass transition temperature, while decreased in tanδpeak and breaking tensile elongation. The damping of the TiO2/NRR-PVC hollow fiber were not only linked to the dosage of TiO2, but also related to the degree of dispersion in matrix.
