  • Topic:
    Integration of nanoparticles in films for packaging to improve gas barrier properties

    Background:
    Films used for food packaging must have certain barrier properties against water vapor and oxygen. Imagine that crispy potato chips suddenly become labile in the packaging due to bad barrier against water vapor. In order to achieve these good barrier properties, films with several different layers are currently used, which offer exactly this barrier, but also have a serious disadvantage: very poor recyclability.

    Films consisting of layers from only one type of material, on the other hand, can be recycled very well, but tend to offer poorer barrier values. A proven possibility to improve the barrier properties is the coating of the films at very low layer thicknesses.

    Aim of the Thesis:
    The aim of this thesis is to improve the barrier properties of mono-material based films by lacquering. This is to be achieved by integrating nanoparticles into the coating resins to extend the diffusion path. After an extensive literature search on the current state of the art, the nanoparticles will be incorporated into various coating resins. Subsequently, the polymeric substrate films will be coated at laboratory scale and their barrier properties will be characterized. Based on these results, the films will be analyzed and the influencing parameters on the barrier properties will be evaluated.

    Project Plan:

    • Analysis of the surface of different polymeric substrate materials by contact angle determination and AFM
    • Modification of various lacquers
    • Coating of substrate materials with the produced lacquers
    • Analysis of barrier properties against oxygen and water vapor
    • Analysis of mechanical properties and adhesion
    • Evaluation of the results
    • Optimization of process parameters for film pretreatment and coating material
    • Technical documentation (master thesis, presentation, publication)

    Field of Study:
    Applicants should have basic knowledge of surface chemistry and analysis, sample preparation in chemical laboratories, rheology and material characterization (IR, DSC, SEM, etc.).

    Possible courses of this study would be process engineering, chemical engineering, materials science, nanotechnology, chemistry or a comparable course of study.

  • Topic:
    Layer thickness determination of transparent organic coatings by fluorescence dyes

    Background:
    Measuring the thickness distribution of a rather thin, transparent organic layer on a transparent polymer film can be challenging. Some fluorescence dyes absorb light of a particular wavelength and emit light with a longer wavelength. This property, called fluorescence, can be detected with extremely high sensitivity and therefore, only a very small concentration of a fluorescent dye, added to the organic layer, is sufficient. The detected fluorescence intensity is correlated to the thickness of the organic layer.

    Aim of the Thesis:
    The aim of this thesis will be the monitoring of the emitted fluorescence light intensity of an organic layer as a function of its thickness. The organic material is mixed with a fluorescent dye before processing. The optical measurement system includes an appropriate light source, with an optical detection system. The layer containing the fluorescent dye will be triggered by means of the light source; and the emitted light will be captured by means of the optical detection system. The captured images will be analyzed in terms of the RGB intensities (for a specific selected region of interest), which will then be correlated to the coating layer thicknesses.
    A model will be generated showing the layer thickness dependency on the emitted fluorescence intensity. The achievable resolution of the measurement system will be determined at the minimum reasonable fluorescent dye concentration.

    Project Plan:

    • Preparation of the organic materials with dyes, coatings at various layer thicknesses
    • Measurement and evaluation of the effect of the various optical system parameters on detected signal.
    • Determination of layer thicknesses by means of microscopy
    • Evaluation of the results and generation of models showing the layer thickness dependency on signal intensity.
    • Optimization of the system parameters for a reproducible, accurate layer thickness determination
    • Technical documentation (Master thesis, presentation, Publication)

    Field of Study:
    Applicants should have basic knowledge in optical spectroscopy, photometry, materials and processing, and programming with MATLAB.
    Possible fields of study are Process Engineering, Mechanical Engineering, Physics

  • Diploma, Bachelor or Master Thesis for students in the areas of Chemical Engineering, Chemistry, Bio Process Technology, Mechanical Engineering in the area of Plastics Recycling

    Recycling plastics becomes increasingly more important since fossile resources are limited and harmful emissions have to be reduced. The Department for Process Development for Polymer Recycling at the Fraunhofer Institute for Process Engineering and Packaging in Freising experiments with the solvent-based recycling of plastics (CreaSolv®-Process) and the interaction of solvents and polymers. This process enables us to selectively dissolve out one or several specific target plastics from complex plastic-containing waste materials and to produce ultrapure polymer recyclates.
