1. Simulations of Semi-Crystalline Polymers and Polymer Composites in order to predict Electrical, Thermal, Mechanical and Diffusion Properties
Abstract : Several novel computer simulation models were developed for predicting electrical, mechanical, thermal and diffusion properties of materials with complex microstructures, such as composites, semi-crystalline polymers and foams. A Monte Carlo model for simulating solvent diffusion through spherulitic semicrystalline polyethylene was developed. READ MORE

2. Meso-scale modelling of composites and semi-crystalline polymers
Abstract : This thesis covers the first few steps of a multi-scale computer simulation strategy for predicting physical properties of complex polymers like composites and semi-crystalline polymers. Meso-scale simulations of crystallization and solvent diffusion in polyethylene as well as simulations examining the geometrical impact on the effective permittivity of composites have been performed.

3. Structure and Dynamics of Hydrated Biopolymers
Abstract : Hydrated polysaccharide systems primarily using xylans along with mutans and alternans were studied using long atomistic simulations over a few microseconds to analyse structure-function relationships and nanoscale interactions with moisture. The influence of various structural and chemical factors such as alignment, nature of glycosidic linkage, effect of moisture / chemical substitutions was explored with a focus on structure-dynamics correlations to aid in the effective functionalisation of biomaterials for the development of a green, circular bioeconomy.

4. Plasticization of Biobased Polymers: A Combined Experimental and Simulation Approach
Abstract : The field of bio-based plastics has developed significantly in recent decades and there is an increasing demand for industries to shift from petrochemical to biobased polymers. Biobased polymers offer competitive properties, and in many cases have advantages in terms of cost. READ MORE
