Composite materials with photo-responsive capability

Photo-responsive materials belong among novel, fast-developing intelligent materials of modern era. They seem to be promising smart systems in many current and future technologies i.e. in medicine, mechanical and construction engineering, energy harvesting, sensors etc. Very encouraging group of these materials is represented by photo-actuating (PA), shape-memory systems. Their main feature known as photo-actuation is capability to rapidly and reversibly change their shape after external light exposure. However, there are several limitations reducing their real-life utilization. Generally known PA systems, mainly solid materials, suffer from not very significant dimension change that is usually in order of 0.001% of original shape. Hence, the main aim of this work is focused on composite systems, in which the combined PA effect of matrix and filler is frequently synergic, but those systems also possess many drawbacks that need to be solved, i.e. low compatibility of filler to the matrix related poor dispersibility in such system resulting to the low thermal conductivity and finally poor mechanical properties as well as PA capabilities. The mentioned drawbacks can be reduced by modifying the filler with compact polymer layer possessing such surface properties those can significantly enhance particle/matrix compatibility and thus contribute to considerably improve overall properties.
