Organohydrogels - A Horizon Scanning

There is extensive ongoing research in the domain of new materials. One area that has received enhanced interest is gels, specifically organohydrogels. These gels are composed by three-dimensional polymeric networks containing water, organic solvents, and sometimes, other substances in their pores. The number of publications within this area is growing fast. The main driving factors for the increasing interest are the inherent properties of organohydrogels, which makes them possible candidates for a multitude of applications. The material's flexibility, ability for self-adhesion and self-healing as well as its morphing ability are just some of the attributes that makes organohydrogels attractive. Organohydrogels are also temperature resilient and they have high electrical and thermal conductivities. We have performed a horizon scanning of scientific peer-reviewed literature concerning organohydrogels. The focus of the scanning was to find out whether organohydrogels are relevant for further activities at FOI, particularly for applications within future military defence capabilities. The horizon scanning activity was initiated based on the identified trend in the peer-review literature. The findings of the horizon scanning clearly shows that there are numerous military applications where organohydrogels potentially could play a role. Some examples worth noticing are wearable sensors, self-powered sensors and bio-electronic units. This report presents recommendations for future work. It is suggested that FOI continues to follow the development of scientific knowledge in this area, although implementing a wider approach, also comprising other materials with similar properties as organohydrogels. Furthermore, in-depth studies of one or more fields might be considered, with regard to applications of particular interest. In cases where the technology readiness level is sufficiently high, performing a technology forecast could be relevant. Another recommendation is to consider external cooperation. Conducting own experimental research, although limited, may facilitate such cooperation.
