UV‐curable Polyurethane Elastomer with UV‐irradiation/Thermo Dual‐Activated Self‐healability

In this paper, we present a simple bendable resistance sensor with silver nanowires (AgNWs) stripe coated on microgroove surfaces formed on a polyimide (PI) film. We adopted an anisotropic wetting manner to form a narrow stripe in order to improve the sensitivity of the resistance sensor. The ultraviolet (UV)-curable polymer NOA61 is firstly drop-coated on the substrate, and then imprinted by a groove-textured poly (dimethylsiloxane) (PDMS) template. After UV irradiation and de-molding, the surface is further treated with a UV-ozone (UVO) lamp, so that the grooved surface becomes more hydrophilic, which will promote the anisotropic wettability of AgNWs suspension and thereby deposition of AgNWs into uniform multi-layer stripe pattern. Moreover, the conductance with respect to the bending motion is measured. The most variation of conductance ΔG/G0 can reach about 200 % with bending radius of 2 mm.

This work successfully prepared an UV curable organic-inorganic hybrid material consisting of organic modified colloidal silica. Applications of UV curable organic-inorganic hybrid materials include abrasion resistant coatings, photo-patternable thin films and waveguides. Colloidal silica containing reactive functional groups were also prepared by reacting organic silane and tetraethyl orthosilicate (TEOS) using sol-gel process. In addition, the efficiency of grafting organic moiety onto silica nanoparticles was investigated by applying TGA and FTIR techniques. Experimental results indicated a strong interdependence between surface modification efficiency and solution pH. Acrylate-SiO2 hybrid formation could result in a shifting of thermal degradation temperature of organic component from about 200°C to near 400°C. In addition, the stability of organic modified colloidal silica in UV curable formula and the physical properties of resulting coatings were discussed. Furthermore, the morphology of organic modified colloidal silica was investigated by performing TEM and SEM studies‥
