Light-induced and sensing capabilities of SI-ATRP modified graphene oxide particles in elastomeric matrix

摘要: Photoactuators can concern light stimuli in appropriate wavelength into mechanical response. Such reversible changes the material shape are highly promising their applications as remote controllers, or safety sensors. In this work we were focused on light-induced actuation and sensing performance of prepared materials. case poly(dimethyl siloxane) PDMS with various amounts silicone oil curing agent was used matrix. Graphene oxide (GO) filler its neat form well modified analogue concentration 0.1 vol. %. Modified GO particles controllably coated poly(methyl methacrylate) polymer chains using surface-initiated atom transfer radical polymerization (SI-ATRP) approach order improve interactions between matrix which consequently lead to enhanced performance. Generally, both, ones characterized FTIR, Raman spectroscopy finally conductivity measurement confirm controllable coating simultaneously proceeded reduction. By studying dielectric properties (activation energies), viscoelastic properties, investigated dynamic analysis, evaluated connection light-responsive capabilities.
