<![CDATA[The purpose of this study is the manufacture of natural bentoniteinto nano particles and is used as a filer on thermoplastic high-densitypolyethylene ( HDPE ) . The method used in the manufacture of nano-particles of bentonite are two ways ; The first synthesis method usingsurfactant cetyl trimethyl ammonium bromide ( CTAB ) and the secondway in ballmill for 10 hours . Characterization of the particle sizeanalyzer ( PSA ) , morphological analysis with scanning electronmicroscope ( SEM ) and analysis of the structure by X - ray diffraction (XRD ) was performed . Nano particles with variation of composition ofnatural bentonite ( 2 , 4 , 6 , 8 , 10 % w t) blends with HDPE andcompatibilizer PE - g- MA on the appliance 's internal mixer at atemperature of 150 C and laboplatomil rate of 60 rpm for 10 minute.Berdasarkan PSA analysis and X - ray , natural bentonite having an average size of 75 nm for synthesis with CTAB , and 97.5 nm for the ball mill . from the results of XRD analysis of minerals crystoballite (SiO2 ) and phase annite ( Al3.448Fe3K0.99Na 0.01O12Si 2.552 ) . In testing the mechanical properties of the resulting increase in tensile strength and breaking up the composition perpajangan 2 to 6 % and a decline in the composition of 8 % . The results of SEM analysis showed that homogeneous mixing of ingredients and the bentonite particle agglomeration on the composition of 10 % wt. ]]>
