Abstract	Ansam A. Hashim*, Watheq K. Salih* Abstract— High density Polyethylene (HDPE)/Titanium dioxide (TiO2) nano-composite was prepared by melt compounding with a twin screw extruder to detect the anti-bacterial efficiency (E.coli & S.aureus types) and the mechanical properties ( tensile stress & E-modulus ) of this composite. Different weight fractions of Titanium dioxide ( 2% , 4% , 6% wt) were used. The activity of TiO2/HDPE composite against bacteria types was investigated using disc diffusion method. The results showed that highest tensile and E-modulus values (33.35 , 266 MPa ) were recorded for 4%wt sample and it has the highest activity against the bacteria.. Also the results showed that TiO2/HDPE composite is more effective against E.coli bacteria than against S.aureus type. Microscopic images of the prepared samples assured that 4% wt. sample is characterized by a high degree of homogeneity which contributed in this activity and in improving mechanical properties.
