The Role of Anatase Nanoparticles on the Mechanical Properties and the Bacterial Adhesion to Acrylonitrile-Butadiene-Styrene Terpolymer

Such materials are needed in many components in the medical, industrial, and environmental applications. To obtain that combination, high weight percents of anatase nanoparticles, as bacterial adhesion reducer, were incorporated into a matrix of the ABS terpolymer.

Pseudomonas aeruginosa, Staphylococcus aureus, and Klebsiella pneumonia were selected for the bacterial adhesion tests. The surface properties of the composites were investigated and correlated to the adhesion behavior using nonlinear regression technique. It has been found that adding anatase nanoparticles improves the stiffness and the compressive strength of the terpolymer with a noticeable reduction in the flexural strength due to the development of minor defects in the structure.
