Atomic force microscopy temperature variation

Using atomic force microscopy (AFM), Kasai et al. [16] have also investigated how adhesion and friction between snrfaces covered with FDTS and OTS respond to temperature variations. The temperature range investigated was 20°C-115°C. For both the OTS and FDTS monolayers, increasing the temperatnre was shown to decrease both the adhesion and friction between the tip and the snrface. The decrease in both friction and adhesion was attribnted to a loss in the water content within the monolayer. The adhesion and friction forces dropped by a factor of two over the temperature range investigated. 

Figure 5.83. Atomic force microscopy phase images of a propylene/ethylene copolymer recorded at elevated temperatures of (A) 90°C, (B and C) 92.5°C, and (D) 100°C. In all images, the gray contrast covers phase signal variation of 20°. (From Bar and Meyers [170] used with permission of the MRS Bulletin.)...
