ELECTROSPINNING OF COMPOSITE MATERIALS

By

Lasse Christiansen

 

This Ph.D. defence treats electrospinning of composite materials: The aim of this project has been to develop methods to enhance the mechanical properties of aerogel by embedding aerogel particles in a polymer fibre matrix. Different electrospinning variants as a production method for composite insulation materials have been developed. The different electrospinning variants have been tested with different types of aerogel, and the produced fibre materials have been characterised. Various characterisation techniques are used to determine the thermal and mechanical properties of the fibres. The electrospinning variants have also been upscaled by going from single needle prototypes to multi-needle electrospinning in the case of both melt and solvent electrospinning. Furthermore, the defence will address the link between gas permeability and thermal conductivity in fibre materials. The results presented in this thesis contribute to the scientific knowledge of composite material electrospinning, and the understanding of the thermal properties of porous fibre materials. The development of the new production methods can aid future research in and production of electrospun materials.
