We create sustainable, plastic-based product and processes innovations with a focus on high-performance polymers and composites.
We achieve the level of ingenuity required for this by implementing an interdisciplinary approach, fusing together the fields of raw materials, construction and processing. In doing so we approach product development with plastics in a holistic way.
Our expertise in the fields of chemistry and analytics, process engineering and structural mechanics blends very well with the surface structuring and functionalisation expertise of the FHNW Institute of Polymer Nanotechnology.
Research focus areas
Selected projects
We support innovative companies in exploring the latest technologies and methods and in translating them into practical applications. We collaborate with national and international research partners and facilitate access to funding opportunities such as Innosuisse projects or European Union research programmes.
Laboratories
Network and partners
CC Schweiz is the Swiss regional department of Carbon Composites e.V." and was chosen as a national thematic network (NTN) by the Swiss Commission for Technology and Innovation (CTI). CC Schweiz focuses on promoting the use of high-performance fibre composite technologies in Switzerland. Our institute is a founding member and co-initiator of CC Schweiz. Prof. Dr. Christian Brauner is acting President of CC Schweiz.
The Innovation Booster promotes the implementation of 100% circular concepts and solutions in Switzerland. Between 2021 and 2024, the program will support Swiss start-ups and established companies with funding and knowledge transfer, helping them to transform their systems and our society from a linear to a circular economy.Prof. Dr. Christian Rytkais a member of the Innovation Booster Applied Circular Sustainabilityconsortium.
