چکیده انگلیسی


- The adhesion of TNT, PETN and RDX crystals were examined with a range of surfaces.
- Adhesion was examined to both non-textile (n = 5) and textile (n = 10) surfaces.
- The non-textile surfaces were found to be much smoother than the textile surfaces.
- There was a tendency of a higher adhesion to the smoother, non-textile surfaces.
- Particularly high adhesions were observed glass, to the smoothest surface examined.

This paper describes the use of atomic force microscopy (AFM) to investigate the interactions between explosives crystals and different surfaces. Crystals of TNT, PETN and RDX were mounted onto tipless AFM cantilevers and repeatedly brought into contact with a range of surfaces (n = 15), including textile and non-textile surfaces. The adhesion force during each contact was measured, and the results are presented in this work. The results suggest that explosives crystals display a higher adhesion to smoother, non-textile surfaces, particularly glass. This finding may be of use for forensic explosives investigators when deciding the best types of debris to target for explosives recovery.
