Polymer Gradient Materials

This thesis deals with the preparation and characterization of longitudinal polymer gradient materials (PGMs). The inspiration for this work comes from nature: mussel byssus threads are soft-hard gradient biomaterials. These gradient threads are formed by a polyaddition process, show unique mechanical properties and demonstrate how nature solves the engineering problem of connecting two materials of different modulus. Therefore, the adaptation to synthetic polymer gradient materials is very interesting in terms of the development of materials with unique properties. In this thesis, the prepared PGMs were systematically prepared and studied concerning the influence of the gradient structure on the tensile properties. Furthermore, the preparation of biopolymer gradient materials was envisioned for biomedical applications. PGMs were also utilized to continuously change the surface topography. In summary, this work reveals how bulk, longitudinal PGMs can be prepared, analyzed, and adapted to obtain materials with unique mechanical properties, biomedical relevance or tailored topography.
