19.02.2025, Diplomarbeiten, Bachelor- und Masterarbeiten

This master's thesis focuses on the development of sustainable thermosetting resins that serve as environmentally friendly alternatives to conventional petrochemical resins. The project includes the synthesis and modification of a new resin system, as well as the optimization of formulations and curing conditions. The produced materials will be comprehensively characterized, analyzing their mechanical, thermal, and chemical properties.

Conventional thermosetting resins are often based on petrochemical raw materials and are associated with envi-ronmental issues such as limited recyclability and high CO₂ emissions. In light of the growing demand for sus-tainable materials, bio-based and resource-efficient alternatives are becoming increasingly important. The devel-opment of new, high-performance resins from renewable or recyclable raw materials can make a significant con-tribution to reducing dependence on fossil resources and promoting a circular economy.

The goal of this master's thesis is to develop sustainable thermosetting resins with improved mechanical, ther-mal, and chemical properties, providing an environmentally friendly alternative to conventional petrochemical systems. Initially, the synthesis of the new resin system will be optimized (classical organic syntheses), followed by chemical characterization. Subsequently, the curing processes will be optimized to achieve the best possible cross-linking and, consequently, optimal material properties. The produced materials will be extensively charac-terized, particularly concerning their chemical structure (NMR, FTIR, HPLC/GPC, XRD), mechanical stability (tensile, bending), thermal resistance (DSC, TGA), and rheological properties (viscosity). The insights gained are intended to contribute to the development of sustainable thermosetting resins that are both high-performing and environmentally friendly, suitable for various industrial applications.
