Characterization of Rough PTFE Surfaces by the Modified Wilhelmy Balance Technique
Karl, Christian; Krauklis, Andrey; Lang, Andrej; Giese, Ulrich (Peer reviewed; Journal article, 2020)The wetting of rough polymer surfaces is of great importance for many technical applications. In this paper, we demonstrate the relationship between the mean roughness values and the fractal dimension of rough and self-affine ... -
Composite Material Recycling Technology—State-of-the-Art and Sustainable Development for the 2020s
Krauklis, Andrey; Karl, Christian; Gagani, Abedin; Jørgensen, Jens Kjær (Peer reviewed; Journal article, 2021)Recently, significant events took place that added immensely to the sociotechnical pressure for developing sustainable composite recycling solutions, namely (1) a ban on composite landfilling in Germany in 2009, (2) the ... -
Flexible Hybrid and Single-Component Aerogels: Synthesis, Characterization, and Applications
Fijalkowski, Mateusz; Coufal, Radek; Ali, Azam; Adach, Kinga; Petrik, Stanislav; Bu, Huaitian; Karl, Christian (Peer reviewed; Journal article, 2023)The inherent disadvantages of traditional nonflexible aerogels, such as high fragility and moisture sensitivity, severely restrict their applications. To address these issues, different techniques have been used to incorporate ... -
Modelling of environmental ageing of polymers and polymer composites—durability prediction methods
Starkova, Olesja; Gagani, Abedin; Karl, Christian; Rocha, Iuri B. C. M.; Burlakovs, Juris; Krauklis, Andrejs (Peer reviewed; Journal article, 2022)Polymers and polymer composites are negatively impacted by environmental ageing, reducing their service lifetimes. The uncertainty of the material interaction with the environment compromises their superior strength and ... -
Modelling of Environmental Ageing of Polymers and Polymer Composites—Modular and Multiscale Methods
Krauklis, Andrey; Karl, Christian; Rocha, Iuri B. C. M.; Burlakovs, Juris; Ozola-Davidane, Ruta; Gagani, Abedin; Starkova, Olesja (Peer reviewed; Journal article, 2022)Service lifetimes of polymers and polymer composites are impacted by environmental ageing. The validation of new composites and their environmental durability involves costly testing programs, thus calling for more affordable ... -
Plastics in aquaculture: A circular economy guidebook
Lindberg, Helene Øyangen; Grytli, Tuva; Kubowicz, Stephan; Karl, Christian; Lund, Henrik Brynthe; Irgens, Mathias; Kenzhegaliyeva, Assiya (SINTEF rapporter;00797, Research report, 2023)This report presents 25 concepts for making plastics from aquaculture more circular. The concepts are based on industry initiatives, circular business models and management principles. Furthermore, the report describes ... -
Surface Modification of Ethylene Propylene Diene Terpolymer Rubber by Plasma Polymerization Using Organosilicon Precursors
Karl, Christian; Rahimi, Wehid; Kubowicz, Stephan; Lang, Andrej; Geisler, Harald; Giese, Ulrich (Peer reviewed; Journal article, 2020)The effect of Atmospheric Pressure Plasma-Enhanced Chemical Vapor Deposition (AP-PECVD) on Ethylene Propylene Diene Terpolymer (EPDM) with the precursors hexamethyldisiloxane (HMDSO) and tetraethyl orthosilicate (TEOS) on ...
