Abstract

Abstract: One way to reduce sensitivity and also adding special properties to explosives is a coating that depends on either the coating agent type or the usage process. In this work, an insensitive nanocomposite of PETN was prepared with multi‐wall carbon nanotube (MWCNT) and Triton X‐114 (TX114) by the solvent/nonsolvent method. Taguchi experimental design (orthogonal array, L9 ) using impact sensitivity (H50 ) investigation was applied to the process optimization. The variable effects of MWCNT mass fraction, solvent (acetone) flow rate, surfactant type and surfactant concentration were evaluated and then the results were quantified by the analysis of Variance (ANOVA). ANOVA data predicted the best H50 was 84.03±3.43 cm that was obtained for the optimum conditions of 5.0 wt% MWCNT, 1 mL min −1 flow rate, TX114 as surfactant with a concentration of 1.0×10 −3 mol Lit −1 . Practical results of H50 were obtained 84.0±0.5 cm that were in agreement with the predicted H50 . Finally, thermal analysis and vacuum stability test were applied to the synthesized nanocomposite and the obtained results indicate MWCNT and TX114 are thermal adaptable and chemically compatible with PETN.
