“…The incorporation of the photocatalysts MoS 2 –rGO/ZnO and BiOBr/g-C 3 N 4 changed the water contact angle of the film and exhibited a significant decreasing trend, promoting the hydrophilic performance of the film toward degrading pollutants. 48 This performance enhancement accelerated the water permeation process, improved the common PFC photocatalytic reaction process to a certain extent, and effectively hindered the fouling effect of organic pollutants in the film.…”

“…Widely used nanofillers can be classified as piezoelectric particles such as lead zirconate titanate (PZT) and zinc oxide (ZnO), which can be used as a nucleating agent to increase the β-phase content. Conductive particles, such as mxene, carbon nanotubes, and metal nanoparticles, can improve the electronic carrying capacity of materials. Other functional materials, such as polydopamine (PDA), poly(methyl methacrylate) (PMMA), and phosphoric acid, ,, were also used to modify the surface to improve interfacial copromotion ability.…”

Tourmaline is known for its natural negative ion effect and far-infrared radiation function, which promote human blood circulation, relieve pain, regulate the endocrine system, and enhance immunity and other functions. These functions motivate the use of this material for enhanced sensitivity of wearable sensors. In this work, taking advantage of the unique multifunctions of tourmaline nanoparticles (Tur), highly boosted piezoelectricity was achieved by incorporating polydopamine (PDA)-modified Tur in PVDF. The PDA@Tur nanofillers not only effectively increased the β-phase content of PVDF but also played a major role in significantly enhancing piezoelectricity, wettability, elasticity, air permeability, and stability of the piezoelectric sensors. Especially, the maximum output voltage of the fiber membrane with 0.5 wt % PDA@Tur reached 31.0 V, being 4 times that of the output voltage of the pure PVDF fiber membrane. Meanwhile, the sensitivity reached 0.7011 V/kPa at 1−10 N, which was 3.6 times that of pure PVDF film (0.196 V/kPa). The power intensity reached 8 μW/cm 2 , being 5.55 times that of the pristine PVDF PENG (1.44 μW/cm 2 ), and the piezoelectric coefficient from d33 m/PFM is 5.5 pC/N, higher than that of pristine PVDF PENG (3.1 pC/N). Output signal graphs corresponding to flapping, finger, knee, and elbow movements were detected. The response/recovery time of the sensor device was 24/19 ms. The piezoelectric nanogenerator (PENG) was capable of charging multiple capacitors to 2 V within a short time and lighting up 15 lightemitting diodes bulbs (LEDs) simultaneously with a single beat. In addition, a 4 × 4 row−column multiplexed sensor array was made of PENGs, which showed distinct responses to different stress areas in different sensor modules. This study demonstrated high-performance PDA@Tur PVDF-based PENG being capable of energy harvesting and sensing, providing a guideline for the design and buildup of wearable self-powered devices in healthcare and human−computer interaction.

BackgroundIn our rapidly expanding society, the demand for clean water has steadily emerged as one of the most critical issues, promoting the development of numerous water treatment strategies.AimsCoupling photocatalysis and membrane separation technology provides an energy saving and environment‐friendly as well as sustainable method for aqueous pollutants removal due to the synergetic enhanced pollutant removal efficiency and improved anti‐fouling performance. It is of great scientific and technical significance to construct multifunctional photocatalysis‐membrane separation reactor systems (PMRs) with both the high photocatalytic activity and the strong stability.DiscussionHerein, in order to introduce the recent advances of this field, we present a critical review on developments of PMRs for aqueous pollutant removal, which includes photocatalysts and membranes, advanced methods for designing PMRs. Meanwhile, the recent applications of PMRs in aqueous pollutant removal, antifouling strategies, and mechanisms have also been summarized, including the latest development of PMRs coupling with other treatment methods. Furthermore, future perspective of PMRs is outlooked and predicted.ConclusionPMRs, designed for the removal of aqueous pollutants, offer a more promising solution for the sustainable development of our society in the future.
