“…Environmental Science: Water Research & Technology Paper experimental results that there was no significant difference in dew productivity of samples with different cavity intervals. This indicates that the variation of spacing between cavities has no enhancing or weakening effect on droplet growth, which verifies the conclusions from Hu et al 23 and Lee et al, 24 that surface wettability and morphology are the main factors accelerating or decelerating the growth of dew droplets.…”

“…That is, TRH cooled down to room temperature and remains in the supercooling state. The supersaturated solution is difficult to nucleate spontaneously due to the high energy barrier of homogeneous nucleation (Figure f). − When the TRH is touched, the type of nucleation is transformed from homogeneous to heterogeneous. The energy barrier of heterogeneous nucleation was much lower than that of the crystallization of TRH, which was initiated easily.…”

Reversible adhesives are widely needed in our daily lives and industrial applications. However, robust and switchable adhesion on rough surfaces with on-demand attachment and detachment remains highly challenging. Here, we report a snail-mucusinspired touch-responsive hydrogel (TRH), whose universal and robust adhesion is triggered by simple contact with the attaching surface. TRH is composed of a polymeric hydrogel and saturated sodium acetate (NaAc) and is prepared by one-pot synthesis. At room temperature, TRH remains in an amorphous and soft state, which allows it to conformally adapt to rough surfaces. The contact with the target surface triggers the crystallization of NaAc, which increases the modulus of TRH by an order of magnitude and interlocks with the target surfaces, achieving an adhesion of up to 204.84 ± 53.98 kPa. Upon heating, TRH returns to a soft state, facilitating easy detachment with adhesion of 5.12 ± 1.34 kPa. Meanwhile, the detached TRH is ready for the next adhesion without the need to be maintained at high temperature. TRH finds applications as a smart material for light-triggered adhesion switching, information encryption, and temperature sensors.

“…The initial nucleation process, leading to the formation of a new crystalline phase, can be divided into homogeneous nucleation (nucleating in the volume) and heterogeneous nucleation (nucleating on foreign surface) [50]. According to the thermodynamic model of nucleation, heterogeneous nucleation has a lower nucleation energy barrier (between supersaturation state and critical state) compared with homogeneous nucleation [51][52][53]. As shown in Fig.…”

Stimuli-responsive hydrogel is regarded as one of the most promising smart soft materials for the next-generation advanced technologies and intelligence robots, but the limited variety of stimulus has become a non-negligible issue restricting its further development. Herein, we develop a new stimulus of “touch” (i.e., spatial contact with foreign object) for smart materials and propose a flytrap-inspired touch-responsive polymeric hydrogel based on supersaturated salt solution, exhibiting multiple responsive behaviors in crystallization, heat releasing, and electric signal under touch stimulation. Furthermore, utilizing flytrap-like cascade response strategy, a soft actuator with touch-responsive actuation is fabricated by employing the touch-responsive hydrogel and the thermo-responsive hydrogel. This investigation provides a facile and versatile strategy to design touch-responsive smart materials, enabling a profound potential application in intelligence areas.
