“…As shown in Figure 5 d, the registered stress for PDMS and its composites varies in a nonlinear fashion as a function of the elongation ratio (λ). This is consistent with previous reports on elastomeric composites with carbon-based nanoparticles; from the resulting curves of the uniaxial tests, the shear modulus and Young’s modulus of the membranes can be calculated as reported elsewhere [ 14 ]. For comparison purposes, the stress curves shown in Figure 5 d are plotted only up to λ = 1.4; notice that the inclusion of CNP clearly modifies the mechanical behavior of the samples.…”

“…Globally, this set of events produce mechanical contraction of the sample, and this is registered by the load cell and graphically represented by a peak in the stress relaxation curve (see Figure 6 b). Similar behavior has been observed in graphene/elastomer composites [ 32 , 33 ] and PDMS doped with carbon soot particles [ 14 ].…”

“…Further evidence of this effect is provided in Figure 6 b, showing the stress registered in each sample for five pulses of the IR laser (optical power of 136 mW). This effect induced by laser light is due to optical absorption of the CNP and subsequent heat release within the polymer matrix [ 11 , 12 , 13 , 14 ]. The inclusion of CNP in PDMS thus provides a means to obtain photothermal effects in an otherwise transparent material.…”

“…The inclusion of carbon nanoparticles and nanotubes in PDMS membranes has led to obtaining photothermal effects, owing to the enhanced optical absorption observed in carbon-based nanostructures and the subsequent heat dissipation within the host polymer matrix [ 8 , 9 , 10 , 11 ]. When irradiated with low power laser light, either focused or guided by an optical fiber, these PDMS-carbon composites show highly localized thermal effects leading to applications such as laser-assisted microfabrication and optomechanical deformation [ 12 , 13 , 14 ]. This capability for generating highly localized thermal effects can be further exploited in photonics for fabrication, activation, and control of a wide variety of devices.…”

Abstract:The advent of nanotechnology has triggered novel developments and applications for polymer-based membranes with embedded or coated nanoparticles. As an example, interaction of laser radiation with metallic and carbon nanoparticles has shown to provide optically triggered responses in otherwise transparent media. Incorporation of these materials inside polymers has led to generation of plasmonic and photothermal effects through the enhanced optical absorption of these polymer composites. In this work, we focus on the photothermal effects produced in polydimethylsiloxane (PDMS) membranes with embedded carbon nanoparticles via light absorption. Relevant physical parameters of these composites, such as nanoparticle concentration, density, geometry and dimensions, are used to analyze the photothermal features of the membranes. In particular, we analyze the heat generation and conduction in the membranes, showing that different effects can be achieved and controlled depending on the physical and thermal properties of the composite material. Several novel applications of these light responsive membranes are also demonstrated, including low-power laser-assisted micro-patterning and optomechanical deformation. Furthermore, we show that these polymer-nanoparticle composites can also be used as coatings in photonic and microfluidic applications, thereby offering an attractive platform for developing light-activated photonic and optofluidic devices.

Stimuli‐responsive polymer membranes have gained particular attention for the ability to tune opportunely their physicochemical properties under the application of an external stimulus. Heat, pH value, ionic strength, pressure, humidity, electric and magnetic fields, antigen/antibody interactions, chemical reactions, and light can be used as triggers for specific responses in polymer membranes. In particular, light is a fascinating stimulus, as it is a green energy, which can be modulated in a precise and convenient way. In addition, it allows remote and contactless interactions without changing the original chemical environment. This review reports recent progresses in light‐responsive polymer membranes with particular attention to chemical groups and responsive mechanisms.
