Abstract:
Polymers have a wide range of applications. Their ability to be shaped into multiple forms makes it possible to obtain polymer films, which are highly used in industries such as food and pharmaceuticals. Characterization of polymer films using the classical mechanical properties is well-defined; however, this is not the case for the fracture properties. The overall aim of this work was to analyze in full-detail the fracture behavior of ductile polymer films by applying the appropriate fracture mechanics approaches. The first part of the thesis aimed to investigate the existing relationships

Abstract During the past decade submicron and nanoparticles have aroused a wide interest and gained new applications due to their high surface area and strength. Grinding with a wet stirred media mill is usually the last process step before the submicron or nanoparticles are added to an application, and the step where the final particle size distribution is achieved. Since stirred media milling is an energy-intensive process, energy efficiency should be optimized. This can be done by determining the optimum operational parameters for the mill and using the highest possible solids concentration
