Hot Embossing

Hot Embossing: Theory of Microreplication, Second Edition presents the current state-of-the-art in microreplication, with a focus on hot embossing, nanoimprint, thermoforming, and roll-to-roll replication. Polymer processing, the theory of polymers and the processing of polymers are discussed in detail. The book contains in-depth analysis of processing processes and replication techniques, including mold fabrication. Monitoring, data analysis and reliability of molded parts is also discussed. In this updated edition, new processes are included, such as the process of micro- and nanothermoforming to generate 3D structures and the hot pulling processes to generate hierarchical structures with high aspect ratios. Based on hot pulling, "Nanofur” for Oil-water-separation is a large-scale biomimetic application. Upscaling, especially the seamless roll-to-roll replication, is also explored. The book is designed to cover the entire workflow for a seamless lithographic sleeve. This new edition marks a substantial update of the previous edition, incorporating several new chapters. It is an important resource for materials scientists and engineers working in the areas of micro- and nanofabrication.

Matthias Worgull is an associated professor and lecturer at the Institute of Microstructure Technology, Karlsruhe Institute of Technology, Germany and has more than 20 years of experience in polymer micro structuring by replication processes. He is currently head of the group "Large Scale Structuring" with focus on the upscaling of hot embossing, nanoimprint, and roll-to-roll replication and the implementation of functional bionic surfaces with enhanced materials.
