In this paper, we report a facile approach to prepare magnetic gel based on the simultaneous formation of Fe 3 O 4 nanoparticles and crosslinking of natural peach gum polysaccharide . The obtained magnetic gel with porous structure, high specific surface area and numerous oxygen-containing functional groups exhibited fast and efficient adsorption capability towards Pb 2+ and Cd 2+ ions. The adsorption isotherms and kinetics presented good correlation with Langmuir isotherm and pseudo-second-order model, respectively. The maximum adsorption capacity of the magnetic gel for Pb 2+ and Cd 2+ ions can reach 277.0 and 141.4 mg g −1 , respectively, which is much higher than many other reported magnetic adsorbents. In addition, the magnetic gel can serve as a magnetic support for in situ growth of Pt nanocatalyst with high catalytic activity, as demonstrated by the reduction of 4-nitrophenol. Moreover, the magnetic gel exhibited excellent magnetic separation capability and superior reusability both for the adsorption and catalysis applications.

The binder plays a crucial role in maintaining electrode structure and improving the cycling performance in Li S batteries , especially for high–energy–density batteries. Here, a natural biopolymer peach gum (PG) was developed as sulfur cathode binder for the first time. PG binder owns abundant carboxyls and hydroxyls, which can form strong interaction between Li O and further effectively constrain polysulfides from shuttling. Besides, strong adhesion force and superior mechanical behavior of PG help to keep the electrode integrity and good electrical contact. Therefore, PG@S electrode achieves an impressively high discharge areal capacity of 27.10 mAh cm −2 with sulfur loading of 26.3 mg cm −2 .

To overcome low adsorption capacity, slow adsorption rate, poor adsorption selectivity, and dissolution of peach gum polysaccharide (PGP), an amino-rich crosslinked PGP (ACPGP) was first synthesized by cross-linking highly soluble PGP. Subsequently, a cation-rich PGP (QCPGP) was prepared from ACPGP through the addition of glycidyltrimethyl ammonium chloride (GTAC) and a secondary quaternization. The step-by-step preparation process was confirmed, and the adsorption properties of PGP, ACPGP, and QCPGP were compared in detail. The adsorption of crude PGP for cationic dyes violet (MV, 135.0 mg/g) and methylene blue (MB, 121.4 mg/g) were spontaneous endothermic, following the pseudo-first-order kinetic model and D-R isotherm. Due to the presence of rich charged groups in their structure, their highly selective adsorption towards new coccine (NC) and tartrazine (TTZ) is spontaneous and endothermic, and can be described by the pseudo-first-order and pseudo-second-order kinetic models, respectively. According to the Langmuir isotherm, the Q m of ACPGP and QCPGP for NC and TTZ was calculated to be 876.2 and 1304.3 mg/g (NC), and 814.5 and 1136.7 mg/g (TTZ), respectively. QCPGP exhibited more advantages in terms of adsorption capacity, adsorption rate (equilibrium time of 10 min), environmental stability, adsorption selectivity, and regeneration efficiency, showing great potential in practical wastewater treatment applications.

Restricted by the poor solubility and complex structure, it remains a significant challenge to efficiently convert raw peach gum (RPG), a natural plant gum comprised of polysaccharides, into usable polymer materials. Herein, a novel approach is reported to prepare UV-responsive peelable pressure-sensitive adhesives (PSAs), which are mainly applied in the manufacturing of ultrathin electronics, through efficient utilization of RPG via prior dissolution using the N,N -dimethylacetamide/lithium chloride (DMAc/LiCl) solvent system and later degradation using H 2 O 2 under UV light at room temperature. With sorbitol-based polyurethane acrylate (SPUA) as a UV-curable oligomer, rosin as a tackifier, and epoxidized soybean oil (ESO) as a plasticizer, before UV irradiation, the 180° peel strength of the prepared PSAs reached 244.4 N/m. A short period of UV irradiation caused a formed cross-linked network structure inside the PSA and a disruption of the adhesive interface, resulting in a sharp decrease of 180° peel strength to 7.3 N/m to achieve a non-destructive peeling of the adherend electronics from the carrier. This work provides a feasible strategy for efficiently utilizing natural peach gum to prepare bio-based UV-responsive peelable PSAs.

The increase in nondegradable polymer waste and the depletion of nonrenewable fossil resources result in environmental concerns and unsustainable industrial development. It is significant to fabricate polymer thermosets with degradable, self-healable, weldable and recyclable performances from biomass. Herein, for the first time, natural peach gum (PG) as an attractive feedstock was employed to prepare degraded and recycled polyimine (PI) networks, due to the hydrolysable and renewable nature of PG. Firstly a peach gum polysaccharide with pendent –CHO groups (PGP-CHO) was synthesized through a graft reaction between 4-formylbenzoic acid and PGP; then it was cured with chitosan (CS) via a moderate and catalyst-free Schiff base reaction resulting in fully biobased PI networks (PGCS). The resultant PGCS-100 networks display good mechanical properties (tensile strength of ∼56.5 MPa and Young's modulus of ∼439 MPa) and high thermal stability (initial decomposition temperature around 227.1 °C). Meanwhile, the PGCS-100 network containing the most dynamic imine bonds exhibits superior self-healing, welding, shape memory and reprocessing performances. Moreover, PGCS-100 can be degraded completely under acidic conditions, allowing sustainable recycling. Furthermore, PGCS-100 can be applied in recycled adhesion, exhibiting excellent adhesion strength (10.5 MPa). Briefly, a new strategy to develop green environmentally friendly PI networks with high performance from biomass is provided, contributing to the reduction of polymer waste and sustainable industrial development.

This study was aimed at evaluating the potential of peach gum (PG) and gelatin in the microencapsulation of eugenol and the intervention of eugenol microcapsules on hepatic steatosis in vitro. Response surface method (RSM) was used to optimize the encapsulation conditions of eugenol microcapsules. The microcapsules were characterized by scanning electron microscopy (SEM), dynamic Light Scattering (DLS), Fourier transform infrared spectroscopy (FT-IR) and release behavior in vitro was determined. The effect of eugenol microcapsules on free fatty acids (FFA) treated hepatocellular cells (HepG2) cells was evaluated by oil red O staining and intracellular total cholesterol (TC) and triglyceride (TG) determination. The results showed that the optimal encapsulation conditions were as follows: the PG-gelatin ratio was 1.6:1.4, the core-wall ratio was 1.6:1.4, the pH was 4 and the emulsification speed was 9000 r/min. The optimized microcapsules were smooth spherical with a size of about 3.09 ± 0.58 μm and the encapsulation was confirmed by FT-IR. In vitro release behavior showed that eugenol microcapsules could be released stably in a neutral environment for 72 h. Oil red O staining showed that 50 and 100 μM eugenol microcapsules could significantly inhibit the lipid accumulation and reduce the TC and TG in steatotic HepG2 cells induced by FFA. Therefore, PG and gelatin can be used as excellent carriers for the microencapsulation of volatile compounds in the field of biomedical industry, and eugenol microcapsules is a promising preparation for the treatment of nonalcoholic fatty liver disease (NAFLD).

Herein, we demonstrated the potential of peach gum polysaccharide-based amine-rich gel (ARG) as an efficient adsorbent for removal of anionic dyes from water. The adsorption performance of ARG was systematically studied by choosing methyl orange (MO) and amaranth (ART) as representative anionic dyes. The effects of various parameters such as pH, ionic strength, temperature, initial dye concentration and contact time on the adsorption were investigated. The ARG exhibited superior adsorption selectivity and stable adsorption behaviors against variation of pH and ionic strength for anionic dyes. Adsorption process reached equilibrium within 10 min and showed good correlation with pseudo-second-order kinetic model and Langmuir isotherm. The adsorption capacity of ARG for MO and ART can reach 1949.5 and 1082.2 mg g −1 , respectively. Based on its sustainable characteristic, low cost and excellent adsorption property, the ARG holds great promise for utilizing as an adsorbent for practical water treatment applications.

Despite impressive progress of macromolecular encapsulation technique based on hyperbranched polymer (HP), the use of natural HP for guest encapsulation has rarely been reported. Herein, we present the simple synthesis of amphiphilic PGP-DC from natural peach gum polysaccharide (PGP) and demonstrate that the PGP-DC can be utilized as a robust host for encapsulation of dye molecules from water. The influences of initial dye concentration, dosage of PGP-DC, pH, ionic strength , and encapsulation mode on the encapsulation were systematically studied. The PGP-DC simultaneously exhibited fast encapsulation rate and superior encapsulation capability. Under optimal conditions, the encapsulation capacity of PGP-DC towards methylene blue (MB) (1 mM) can reach as high as 182.67 mg/g, which compares favorably to other separation techniques. Moreover, the MB-encapsulated PGP-DC could be well regenerated in acidic solution. Based on its simple synthetic process, excellent encapsulation performance and fine reusability, the PGP-DC holds great promise for using as a host for practical encapsulation applications.

Given their environment friendliness, light weight, and availability, bio-films have attracted wide interest for various applications in sensor materials. However, obtaining sensors with good environmental stability, excellent flame retardancy, and high wet strength remains a challenge. Herein, we prepared sensitive water, temperature and flame-responsive multi-function bio-films (named as PSCG bio-films) by combining peach gum polysaccharide , silk nanofibres, citric acid , and graphene. The PSCG bio-films demonstrated good flexibility, rapid and consistent water absorption, and stable wet strength at different temperatures. The bio-films showed excellent water sensitivity and rapid fire responsiveness within a short time frame (2 s); moreover, the response and recovery times of the bio-films in the temperature range of 50–150 °C were 0.1 and 0.3 s, respectively. In addition, the bio-films can be applied to micro-sized fire early warning devices and personalized breath monitoring. Our work presents a facile and green approach (without toxic solvent) to fabricate multi-function sensors with applications in various industries.

Bio-macromolecule edible films, used as food packaging materials, are essential for maintaining freshness. Peach gum, rich in polysaccharides, exhibits excellent film-forming capabilities but lacks bacteriostatic properties. In this study, chitosan was incorporated into peach gum film as a bacteriostatic agent, and grass carp was utilized as a model to analyse the film’s antibacterial properties. Sensory evaluation, TVB, inhibition zone, and pH changes were analysed to assess the preservation effect of peach gum-chitosan films on grass carp. The impact of chitosan on the structural and physical properties of peach gum films was estimated. Consequently, chitosan was found to enhance the antibacterial properties and certain physical characteristics. Interestingly, with the addition of chitosan, the preservation efficacy improved; however, the water vapour permeability (WVP) of the peach gum films increased by 21.17%, and the structure became smoother. Thus, these findings will aid in the development of polysaccharide-based edible films and offer theoretical support for the packaging industry.

Solar-powered interfacial evaporation is a developing and sustainable technique increasingly utilized in desalination and wastewater purification. This technology involves the creation of cellulose nanofiber (CNF)/polylactic acid (PLA) composite aerogels through the Pickering emulsion approach. Self-floating aero-hydrogel ( E -VGP) with a hierarchical porous structure was formed on a viscous mixture containing polyvinyl alcohol (PVA), peach gum polysaccharide (PGP), and polypyrrole (PPy) via an in-situ polymerization process. Furthermore, by modifying the hydrolysis time of PGP with a hyperbranched polyhydroxy structure, VGP hybrid hydrogels of varying microscopic molecular sizes were produced. Additionally, solar vapor generators (SVG) with diverse macroscopic structures were fabricated using molds. The V8G4-12hP0.2 hybrid hydrogel, synthesized using PGP hydrolyzed for 12 h, exhibited an evaporation enthalpy of water at 1204 J g −1 . This capacity effectively activates water and enables low enthalpy evaporation. Conversely, the macrostructural design allows the cylindrical rod raised sundial-shaped structure of SVG3 to possess an expanded evaporation area, minimize energy loss, and even harness additional energy from its nonradiative side. Consequently, this micro-macrostructural design enables SVG3 to attain an exceptionally high evaporation rate of 3.13 kg m −2 h −1 under 1 Sun exposure. Moreover, SVG3 demonstrates robust water purification abilities, suggesting significant potential for application in both desalination and industrial wastewater treatment.

Solar energy interfacial evaporation represents a promising and sustainable approach with considerable potential for seawater desalination and wastewater treatment. Nonetheless, creating durable evaporators for continuous operation presents a challenge. Motivated by natural self-healing mechanisms, this study developed a novel 3D hybrid aero-hydrogel, which exhibited a self-healing efficiency of 89.4 % and an elongation at break post-healing of 637.7 %, featuring self-healing capabilities and continuous operation potential. Especially, the incorporation of hyperbranched water-soluble polymers (peach gum polysaccharide) endow the final solar water evaporators with a lower evaporation enthalpy of water, resulting in that the refined SVG3, with a notable water surface architecture and an expanded evaporation area, achieved a steam generation rate of 2.13 kg m −2 h −1 under 1 Sun. Notably, SVG2 achieved a high evaporation rate of 2.43 kg m −2 h −1 with the combined energy input of 1 Sun and 6 V, significantly surpassing the rate of 1.96 kg m −2 h −1 without voltage input. The results indicate that electrical energy significantly enhances and synergizes with SVG, facilitating continuous operation both day and night through the combined use of solar energy and electrical input. This study offers insightful perspectives for the strategic design of multifunctional hydrogels for solar water evaporation.
