CTEC prepared an experimental setup for measuring the displacement of the Photo-Mobile Polymer (PMP), while exposed to light. The goal is to observe and quantify the displacement of the PMP in time, when it is exposed to light, and the effect of the light intensity on this displacement. The experimental setup is made of a…
For the realization of the reaction cells a film of PVA about 10 nm was spinned and on which a directional rubbing must be carried out in order to facilitate the alignment of the liquid crystals present inside the photomobile polymers. An automatic system, for the rubbing of polymeric films that have to be used…
Piezoelectric semiconducting nanowires have attracted a lot of attention recently because of their intrinsic enhanced properties compared to bulk materials. For instance, they are more sensible to small forces [1], they show reduced dielectric properties [2] and higher piezoelectric properties [3]. All this combined could potentially increase their efficiency as transducers [4]. Simulations show that…
The use of stimuli-responsive polymeric materials is nowadays a hot topic because of their immense application possibilities. The deformation of PMP are intended to be induced and controlled by impinging ligth by its intensity, polarization state, wavelength. Specifically, PMP actuators change their shape or volume in response to light [1]. We have developed two different…
