“…154,167,168 For example, the interfacial polarization of poly(thioether) and polysiloxane is enhanced by the phase separation structure of the triblock copolymer, thereby improving the dielectric constant. 169 Furthermore, to obtain acceptable insulating strengths for the applications of gate dielectric, films of more than 300 nm are typically needed. 90 Furthermore, some trials have been devoted to manufacture and investigate stretchable dielectrics with high stretchability and permittivity.…”

“…90 Furthermore, some trials have been devoted to manufacture and investigate stretchable dielectrics with high stretchability and permittivity. 154,[167][168][169] Studies have discovered that styrene-ethylene-butylene-styrene (SEBS) employed as a dielectric is extensively accepted given its hysteresis properties and low viscosity relative to other elastic materials. 71,170,171 However, high permittivity for stretchable dielectrics is critical for decreasing the operating voltage, which will be more beneficial for its application in wearable devices.…”

“…Recently, polymeric materials have obtained significant interest in organic electronic materials owing to the advantages of low cost, light weight, solution processability and especially flexibility. [21][22][23] Among organoelectronic polymers, polysiloxane stands out due to the high dielectric constant and electronic inertness, thereby exerting minimal influence on the electronic properties of semiconductors. [24] Consequently, it facilitates to independently adjust both the physical and electronic characteristics of materials.…”

In this study, a series of ladder‐like polysiloxanes are synthesized by introducing double‐chain Si–O–Si polymer as the backbone and the carbazole and triphenylphosphine oxide with high triplet energy as side groups. The ladder‐like structures of polysiloxanes are achieved through a controlled polymerization method that involves the monomer self‐assembly and subsequent surface‐restricted solid‐phase in situ condensation through freeze‐drying. The introduction of siloxane improves thermal stability of the polymers and inhibits the conjugation of the polymers between the side groups, leading to an increase in the triplet energy level. Therefore, all these polymers perform higher triplet energy levels than phosphorescent emitter (FIrpic). The cyclic voltammetry measurements demonstrate that the bipolar polymer exhibits a high highest occupied molecular orbital (HOMO) value of −5.32 eV, which is consistent with the work function of ITO/PEDOT:PSS, consequently facilitating hole injection. Furthermore, the incorporation of triphenylphosphine oxide promotes electron injection. Molecular simulations reveal that the frontier orbital distributions of the bipolar polymer are located on the carbazole and triphenylphosphine groups, respectively, which facilitate the transport of electrons and holes.

“…[10,11] Therefore, a lot of studies are committed to the development of composite elastomers with specific functionalities and performances. [12][13][14] Generally, functional inclusions, such as droplets, bubbles, or particles, [15][16][17][18][19] are implemented into composite elastomers to endow the systems with superior performances, such as large actuation capability, [20,21] high electrical conductivity, [22][23][24] and good mechanical property. [25][26][27] Therefore, composite elastomers derive their unique properties and functionalities from both elastomer matrix and functional inclusions.…”

Elastomers generally possess low Young's modulus and high failure strain, which are widely used in soft robots and intelligent actuators. However, elastomers generally lack diverse functionalities, such as stimulated shape morphing, and a general strategy to implement these functionalities into elastomers is still challenging. Here, a microfluidic 3D droplet printing platform is developed to design composite elastomers architected with arrays of functional droplets. Functional droplets with controlled size, composition, position, and pattern are designed and implemented in the composite elastomers, imparting functional performances to the systems. The composited elastomers are sensitive to stimuli, such as solvent, temperature, and light, and are able to demonstrate multishape (bow‐ and S‐shaped), multimode (gradual and sudden), and multistep (one‐ and two‐step) deformations. Based on the unique properties of droplet‐embedded composite elastomers, a variety of stimuli‐responsive systems are developed, including designable numbers, biomimetic flowers, and soft robots, and a series of functional performances are achieved, presenting a facile platform to impart diverse functionalities into composite elastomers by microfluidic 3D droplet printing.
