(Confocal) Raman Microspectroscopy for the investigation of plastics and plastic welding seams
In addition to a number of basic projects in the field of pharmacological and biotechnological research, the working group in cooperation with mechanical engineering deals with the investigation of the structure-property relationships of laser-welded thermoplastics. Especially the area around the weld seam and the structural changes caused by the welding process are of great interest.
Since Raman microscopy can be used to determine information about structural conditions contact-free and non-destructively, the working group is currently conducting a corresponding principle study. In the future it should be possible to incorporate the information gained directly into an improvement of the plastic welding process. Fundamental investigations will also provide further information in the field of adhesion theories for welded plastic-metal composites.
