Inspired by the chameleon and cephalopod, scientists have developed materials and devices to mimic a function of changing their skin color with environment stimulus. However, the complicated integration of stretch ability, colorchanging and stimulus sensing are commonly required. Herein, by integrating single-layer silver nanoparticles (Ag NPs) array with liquid crystal elastomer (LCE), we develop a facile bilayer-structural device that exhibits the ability of the color change associated with thermal-driven actuation behavior. It indicates that Ag NPs array inlayed into the surface of LCE layer could spontaneously induce a homeotropic orientation of LC molecules, thereby allowing for different deformations associated with the blue-shift of structural color at vertical and hybrid alignment states in bilayer-structural films. The observed blue shift of localized surface plasmon resonance (LSPR) peak which derives from close packed Ag NPs array may be connected to the elongation of gap distances of Ag NPs induced by flat expansion and bent deformation of LCE. Moreover, finite-element simulations are undertaken for understanding of the intrinsic mechanism of the above behavior. The developed color-changing actuators could be a promising candidate for smart environmental-responsive devices such as thermal-camouflage skin and color change actuators.

“…In particular, we performed a green synthesis sonochemical process to reduce Ag ions to form AgNPs by using ultrasonic method without the use of dangerous stabilizing agents such as any reducing agent and surfactant [26]. The breaking of cavitation bubbles under high temperature and pressure and the hydrogen radicals (H*) and hydroxyl radicals (OH*) in the water formed by the ultrasonic effect play an important role in the reduction of Ag ions and the formation of AgNPs [27].…”

In this study, polyethylene glycol/guar gum @ silver nanoparticles (PEG/ GG@AgNPs) were synthesized by using simple sonication method. The nanoparticles were characterized using Fourier-transform infrared spectroscopy (FTIR) and scanning transmission electron microscopy (STEM). The swelling behaviors of nanoparticles were studied in different pHs (5.5 and 7.4). The experimental results were calculated by Fickian diffusion and Schott kinetic models to understand the swelling mechanism and coefficients of the nanoparticles. The results showed that the linear equation of the Fickian diffusion kinetic model was best fit to explain the water diffusion mechanism of the nanoparticle with high correlation coefficient (R 2 = 0.982-0.987). The results confirmed that the swelling degree of nanoparticles were 9.71 g/g at pH 5.5. Also, the results confirmed that PEG/GG@AgNPs can be a good candidate for drug delivery systems in pharmaceutical applications.

“…Silver plays an important role in drug delivery, wastewater treatment, agriculture, biosensor and textile industries [13][14][15] . The synthesis of nanoparticles by various physical and chemical methods, such as ultrasonic irradiation [16] , laser ablation [17] , evaporative cooling [18] , chemical vapor deposition [19] , explosion [20] , impregnation [21] , co-precipitation [22] , sol-gel [23] and deposition-precipitation [24] , has been reported extensively. However, there is still a need for a more economic, commercially and eco-friendly route to synthesize silver nanoparticles.…”

Abstract. In the present study, the silver nanoparticles (AgNPs) were biosynthesized using tea polyphenols in the silver nitrate solution. The tea polyphenols, which was extracted from the green tea leaves, acted as both reducing (from Ag + to Ag 0 ) and capping agent in the liquid phase. The synthesized AgNPs were characterized with UV-visible absorption spectrum, TEM, EDS spectrum and particles size distribution analysis. UV-visible absorption spectrum indicated a significant absorption peak at 425 nm related to the great synthesis of AgNPs in the aqueous solution. TEM images show the diameter of well dispersed AgNPs was around 28nm. The important parameters including pH value, silver nitrate concentration and temperature affected the synthetic reaction of AgNPs significantly. The AgNPs showed excellent catalytic activity in the degradation of Acid Violet 7 by NaBH 4 , and more than 97% Acid Violet 7 was degraded within 18 minutes.
