Stimuli responsiveness of electron irradiated gelatin — •Stefanie Riedel^1,2, Emilia I. Wisotzki^1,2, Katharina Apel¹, Wolfgang Knolle¹, and Stefan G. Mayr^1,2 — ¹Leibniz-Institut für Oberflächenmodifizierung, Leipzig — ²Fakultät für Physik und Geowissenschaften, Universität Leipzig

Stimuli responsive materials have attracted considerable interest during the past years due to their potential use in sensor and actuator applications. They are designed to transform small external stimuli e.g. temperature and humidity changes into a significant response.

While a large number of alloys or synthetic polymers are well-established at this point, we explore the potential of the biomaterial gelatin to respond to humidity changes. We demonstrate how irradiation with high-energetic electrons allows fine-tuning of the response. In addition, this treatment enhances thermal stability providing high attractiveness for biomedical applications.
