Hierarchically structured materials for sustainability

Heiner Friedrich

Eindhoven University of Technology, Neetherlands

Advanced functional materials are at the core of chemistry and engineering research to address societal challenges related to health, energy, and sustainability. One common feature of current advanced materials is that they are structured not only on one, but over multiple length scales. This is on account that functional properties (mechanical, mass and energy transport, catalytic, optical, and others) can be optimized for specific applications by tuning the materials multiscale composition and morphology. While in the past the focus was mainly on the functionality of materials, future solutions need to be sustainable, e.g., by using resources that are abundant, biocompatible and/or renewable such as carbon- and silica-based building blocks. To realize materials with optimized and/or new functionalities that are made from sustainable building blocks, being able to rationally organize building blocks over multiple length scales within a well-defined structural hierarchy will be of utmost importance. In this lecture I will discuss, from a colloidal perspective, our research into hierarchical structuring of materials. In addition, I will highlight the importance of quantitative (in-situ & 3D) microscopy to gain fundamental insights into process dynamics, materials morphology and functional properties.
