Development of Functional Polymer and Nanocomposite 3D-architectures by MultiPhoton Laser Structuring for Advanced Applications in Microdevices
Final Report Abstract
Advancing the development of novel functional components, particularly their precise miniaturization and facile integration into microdevices, is crucial for continued technological progress. This project focused on the development and investigation of new functional materials and 3D microstructures based on hybrid polymers, nanocomposites, and nature-inspired materials. Multiphoton laser structuring (MPLS) was used as the fabrication technique, enabling high pattern resolution and true freedom in the 3D design of the polymeric microstructure. The properties of the fabricated 3D elements were analysed using a range of highly sensitive techniques to identify those with notable performance. Within the project, a variety of advanced materials were developed, and protocols for their microfabrication were established. The material properties of the resulting 3D prints were examined to assess the complex range of effects caused by material chemistry and fabrication parameters. The morphology, thermal and mechanical properties, time-dependent behavior, and post-modification capabilities were evaluated using high-resolution and high-precision methods. These include various AFM modes, electron microscopy, fast scanning calorimetry, photothermal IR spectroscopy, EDX, XPS and confocal fluorescence microscopy. The multifunctionality and sensing potential of MPLS microfabricated mussel-inspired materials were demonstrated. The results of this project contributes to a better understanding of the underlying physical and chemical mechanisms involved during the fabrication process. By exploring the resulting relationships of the structure-property behaviour, new MPLS advanced functional materials and development strategies were proposed.
