“…The attempts are being made to use polymer composites with fillers providing a wide range of absorption [16, 17]. Carbon black (CB) as a filler material has a wide range of absorption from UV to IR [18, 19], which could lead to a photoactive composite. Also, polydimethylsiloxane (PDMS) is one of the best polymer materials, and there is a lot of research on the properties of PDMS nanocomposites [20, 21], but not for photo‐actuator studies.…”

Materials such as carbon black (CB), carbon nanotube, graphene, etc. have been found to deform on exposure to the light source. Introducing these materials into polymers could convert them to photo-responsive composites. This is demonstrated by the experiment in which polydimethylsiloxane (PDMS) polymer containing CB nanofiller composites is prepared, and its photomechanical actuation from exposure to IR light source is recorded using a laser displacement sensor. The particle size analysis reveals the size of the CB, which is verified by the dynamic light scattering method. The UV-vis-IR spectrophotometer study shows that an increase in the light absorbance capacity of nanocomposites compared to the plain polymer. The PDMS/CB nanocomposite beam exhibited a significant deformation compared to plain PDMS. Deformation of the order of 10-11 mm is observed for a given IR source. The deformation found to have good repeatability but with some thermal hysteresis in cyclic actuation and de-actuation.
