“…Materials capable of changing its dimensions, upon encountering certain external stimulus, reversibly belongs to the group of smart materials [1,2]. Such deformation can be controlled using various stimuli such as electric [3,4] or magnetic field [5,6], humidity [7,8], temperature [9,10], and light [11,12,13]. From these stimuli, only the humidity, temperature and light-induced deformation provide a non-contact deformation, thus, creating various very-specific applications [14,15].…”

This study serves to combine two approaches into one single step, to achieve a significant improvement of the light-induced actuation capabilities. Graphene oxide (GO) is an inert material, from the electrical and thermal conductivity point of view, and is incompatible with the usually-used poly(dimethylsiloxane) (PDMS) matrix. During surface-modification by surface-initiated atom transfer radical polymerization, the GO was transformed into a conducting and compatible material with the PDMS showing enormous light-induced actuation capability. The GO surface-modification with poly(2-(trimethylsilyloxy)ethyl methacrylate) (PHEMATMS) chains was confirmed by transmission electron microscopy and thermogravimetric analysis, with an on-line monitoring of gasses using FTIR. The improved compatibility was elucidated using contact angle and dielectric properties measurements. The PHEMATMS shell was investigated using gel permeation chromatography and nuclear magnetic resonance. The improved electric conductivity was measured using the four-point probe method and by Raman spectroscopy. The very important mechanical properties were elucidated using dynamic mechanical analysis, and with the help of thermo-mechanic analysis for the light-induced actuation. The excellent actuation capabilities observed, with changes in the length of around 0.8% at 10% pre-strain, are very promising from the point of view of applications.

Although titanium oxide has a high dielectric constant, ordinary titanium oxides are not a good electrorheological (ER) fluid material. Herein, hollow peanut-like titanium oxide spheres are synthesized by hydrothermal method, and then coated with silicon oxide to form core-shell hollow TiO 2 @SiO 2 spheres. The structure is characterized by different methods, and the TiO 2 @SiO 2 composite particles are dispersed in silicone oil to prepare an ER suspension. The ER effect of 10% TiO 2 @SiO 2 -based ER fluid under different electric field strengths is tested, and its performance is analyzed. The results show that the coated particles significantly enhance the current meter performance. The shear stress value exceeds 200 Pa at an electric field strength of 3.0 kV mm À1 . The shear stress, shear viscosity, switching effect, and dielectric behavior of the base ER fluid are studied. And, the cause of this strong ER effect is studied. In the end, it is found that TiO 2 @SiO 2 peanut-shaped composite core-shell particles have a good ER effect and which is a kind of ER candidate material with simple preparation and development prospect.
