Surface Roughness and Haze

AFM Imaging of Processed Polymers (2) Surface Roughness and Haze 

The AFM is set up for a standard CM experiment (Sect. 3.2.2). To be able to address the morphology and roughness on various lateral length scales, a large area scanner is selected. After the sample (film firmly attached to the sample puck with double sided sticky tape) has been mounted, care has to be taken to note the relative orientation of cantilever and characteristic film directions (e.g. the machine direction). 

The engagement procedure is carried out with minimized forces as described in Sect. 3.2.2. After engagement, the gains and the scan rate must be optimized. It is advisable to image the films in constant force mode with minimized forces in order 

For the processed iPP films, TM-AFM reveals clearly the nearly vertically oriented marks of the calendering rolls on the polymer films, as well as the
