A plant derived bio-macromolecule namely lignin (L) and a green phosphorus compound like phytic acid (PA) were functionalized with graphene oxide (GO) and subsequently, used to enhance the flame retardant properties of polyamide 66 (PA66) fabrics in a one pot deposition method. Meanwhile, we also considered pure phytic acid and one more bio-derived charring agent like chitosan (CS) to formulate a series of GO-based flame retardant finishing by altering the applied compounds in the formulation. The applied finishing with a minimum loading % (i.e., less than 10%) rarely altered the physical properties (i.e., color, handle and tensile strength , etc.) of treated textiles while provided enhanced thermal stability and added flame retardancy. Thus, a significant increase in limiting oxygen index (LOI) by 27% was received for the GO-lignin and GO-phytic acid modified fabric sample (i.e., PA66-A), indicating the supremacy of graphene-based compound. Furthermore, a substantial reduction in the peak heat release rate (pHRR) by 25% was also noticed for the fabric sample treated with GO-lignin, chitosan and phytic acid (i.e., PA66-D). Additionally, the as prepared finishing exhibited a considerable level of wash durability as a maximum reduction of pHRR by 17% was retained even after 5 washing cycles.

Carbon dioxide-derived non-isocyanate polyurethane (NIPU) foams have attracted wide attention because of their remarkable benefits for sustainable development and green production. While progress has been made in synthesizing NIPU to replace petroleum-based counterparts, challenges persist in achieving high-performance, multifunctional, and recyclable NIPU foams through an eco-friendly foaming process. In this study, we present a green fabrication protocol employing a solvent-free process with HFO-1233zd(E) as an eco-friendly blowing agent, foaming at mild foaming temperatures that reduce the impact on the environment. For the first time, we propose a method that combines renewable biomass components—cellulose nanocrystals (CNC) and phytic acid—with NIPU. This combination synergistically enhances mechanical strength (showing a threefold improvement compared to CNC-free foams), flame retardancy (exhibiting self-extinguishing behavior), thermal stability (with a 15 % residual mass), and unconventional fluorescence properties. A systematic investigation using small-amplitude oscillatory shear rheological analysis allowed for precise modulation of the critical balance between gelation kinetics and foaming dynamics. Through this optimized protocol, we overcome the limitation of NIPU foams, which traditionally served a single function, by simultaneously achieving thermal insulation, flame resistance, and fluorescence. The catalyst-free circularity of the process enables foam reprocessing through the presence of abundant hydroxyl groups and autocatalytic tertiary amines of PEI, eliminating the need for additional catalysts. The biomass-derived additive system, combined with dynamic covalent networks, establishes a sustainable paradigm for developing advanced multifunctional foams, thereby broadening their applications in fields such as architecture, home furnishing, shipping, and packaging.

Peroxidase , a key enzyme causing enzymatic browning, and affected the potential values of fruit and vegetables. Phytic acid and NADH inhibited peroxidase in a competitive manner due to their reducing properties, and it's IC 50 (1.18 ± 0.32) × 10 −8 , (8.02 ± 0.45) × 10 −6 mol L −1 , respectively. The interaction between phytic acid, NADH and peroxidase contributed to intrinsic fluorescence quenching and conformation alternation with a accuracy determination by multispectroscopic techniques (fluorescence spectra, FT-IR and CD spectra), respectively. Molecular docking simulation revealed that phytic acid, NADH interacted with His170, Ala34, Arg38, Ser73, Arg31, Lys174, Gln176, Asn175, Arg75; Gln176, Asn175, Phe221, Lys174, Gly173, Ser167, Phe172, Gly169, His170 in peroxidase, respectively and blocked substrates into catalytic reactions.

Starch, being one of the most abundant polysaccharides in nature, has been modified as starch-based thermoplastic materials for decades. In this work, we have demonstrated a green and facile method for choline phytate (CPA), which is not only a fire retardant but also a plasticizer for starch. Thermoplastic starch (TPS) plasticized with glycerol, CPA, and water was prepared by melt blending. The plasticizing effect was investigated by crystallinity calculation and a tensile test. Also, the flame retardancy of CPA for TPS films was evaluated by combustion tests. As the CPA loading increased, the crystallinity of TPS films decreased from 11.7% to 7.6%. With the addition of 30 phr CPA, the TPS film could pass a UL-94 V-0 rating (1 mm) and the limiting oxygen index was increased to 43.7%. Cone calorimeter characterization revealed that the heat release of SGCPAX composites was efficiently restrained by CPA. The peak of heat release rate was decreased by 68.7% and total heat release was decreased by 33.8% for the TPS films containing 20 phr CPA. The flame-retardant mechanism of CPA in TPS played the key role by the analysis of the char residues.

Physicochemical modification of biomaterials has enormous potential for enhanced functionality and applications. Phytic acid (PA) is a sustainable, non-toxic, and environmentally friendly material used for surface modification in different applications. However, the impact of PA on the surface of the biomaterial matrix and its response to nerve cells has not been studied as far as we know. In this study, we fabricated PA-embedded polycaprolactone (PCL) nanofibrous scaffolds using the electrospinning method and studied the potentiality of these scaffolds for primary sensory neuron growth and alignment. The nanofiber morphology of the scaffolds was evaluated using field emission electron microscopy (FESEM). The results showed that the fiber orientation and diameter were dependent on the amount of PA in the electrospinning solution. The degree of orientation of the aligned nanofibers was higher than that of their random counterparts in composite scaffolds. The PA-loaded nanofibers were found to have higher compatibility with dorsal root ganglia (DRG) neuron cells than the corresponding fibers without PA. Further, the PA provided guidance for axon growth along the matrix. Overall, the results suggested that embedding PA into the scaffold could be a better approach for enhancing nerve growth and alignment, which is required for nerve regeneration.

To obtain rapeseed protein with low phytic acid (PA), soy protein isolate (SPI) was used to investigate the interactions between SPI and PA. The influence of pretreatment (soaking using salt solution and dialysis) of the defatted rapeseed meal on the PA and protein content in the final rapeseed proteins was also studied. The results showed that electrostatic interactions dominated the protein–PA interaction, which was affected by pH and ionic strength. Accordingly, the pH and ionic strength in the soaking medium also influenced the PA remained in the rapeseed proteins. The PA content decreased with the ionic strength (400–800 mM) and relatively low PA was obtained at pH 6.0 (soaking environment). Finally, 52.8 % of the PA have been removed and PA content remained in rapeseed protein isolate (RPI) reached about 0.84 mg/g, at the same time, the protein content was maintained around 86.70 %. Overall, soaking using salt solution and dialysis could be an effective method to achieve high quality rapeseed protein with low PA.

In this study, phytic acid (PA) and 1,10-diaminodecane (DAD) were neutralized in a single step to develop the biobased ionic complex PA-DAD, which was then utilized as a toughener to increase the toughness of epoxy resin (EP). As a result of the sacrificial ionic bonds between DAD and PA, the fracture toughness of composites containing PA-DAD was substantially enhanced. Compared to neat EP, the tensile and flexural toughness of composited EP increased by 697 and 1028%, respectively, when PA-DAD was added at 6 wt %. Additionally, impact, tensile, and flexural strengths were enhanced by 201, 42, and 45%, respectively. Moreover, the modified EP had favorable flame retardancy due to the high phosphorus concentration of PA-DAD. The EP/6% PA-DAD showed a 27.7, 24.2, and 29.6% decrease in total smoke production, total heat release, and peak heat release rate, respectively, as compared to neat EP. The results of this investigation suggested a simple approach to toughening EP systems, which would expand the use of biobased tougheners.

Abstract A Cu-PP hydrogel with 3D network was synthesized using a simple in-situ polymerization method. PA (phytic acid) acts as the dopants and crosslinking agent to form PANI-PA (polyaniline-phytic acid) hydrogel via in-situ polymerization of aniline. PA is also used as a chelating agent to coordinate with Cu 2+ ion due to the high coordination capacity. When irradiated by light, Cu 2+ was slowly reduced to form Cu NPs, distributing uniformly in the 3D matrix of PANI-PA. The 3D network nanostructure ensures a complete contact between the photocatalyst and water, promoting the separation of electrons and holes. The introduction of PANI-PA improves the separation efficiency of electron-hole pairs, where PANI-PA acts as a hole reservoir to trap the holes generated by Cu NPs, hindering the recombination of electron-hole pairs. The Cu 0.2 -PP hydrogel with a copper content of 30.8% exhibits the best hydrogen production rate (6.09 mmol·g −1 ·h −1 ), which is 6.7 times greater than that of pure Cu NPs. Graphical abstract

In this work, epoxy coatings containing phytic acid-doped tetraaniline (PATA) nanoparticles for Q235 steel were prepared and their anticorrosive properties were investigated. Synthesized PATA nanoparticles were characterized by scanning electron microscope (SEM), scanning probe microscope (SPM), photoelectronic spectroscopy (XPS), and Raman test. The anti-corrosion properties of coating were studied by the open circuit potential (OCP), electrochemical impedance spectroscopy (EIS), and scanning vibrating electrode technique (SVET). The experimental results showed that the content of the PATA nanoparticle has a positive effect on the barrier ability of the epoxy matrix. The epoxy coating containing 0.25 wt% of PATA nanoparticles has superior corrosion protection property and a satisfactory self-healing effect. The self-healing effect of PATA/EP coating ascribes to the synergistic effect of the passivation of phytic acid ions and tetraaniline. As an effective anticorrosion filler, the PATA nanoparticle has the potential to apply to the field of corrosion protective coating.

Phytic acid mainly exists in seeds, roots and stems of plants, which has a potential value in flame-retarding polymers due to the high content of phosphorus. In this work, a novel bio-based phytic acid salt PHYPI was prepared through a salt formation reaction between phytic acid and piperazine . The structure of the bio-based PHYPI was verified using 1 H NMR spectrascoppy. When PHYPI was used to fabricate flame-retardant polypropylene (PP), it showed high efficiency in combustion tests. The limiting oxygen index (LOI) value for PP containing 18.0 wt% PHYPI is 25.0%, showing a 38.9% increase compared to 18.0% for PP containing no additive. Moreover, it passed the UL-94 V-0 rating in the vertical burning test, superior to the no rating for pure PP. Obviously, the flame-retarding efficiency of PHYPI is higher than that of typical traditional intumescent flame retardant containing ammonium polyphosphate or pentaerythritol . Cone calorimeter test revealed that the heat release and smoke production of PP were efficiently restrained by the presence of PHYPI. The peak of heat release rate (PHRR), total heat release (THR), and the peak of smoke release rate (PSPR) for PP containing 20 wt% PHYPI were decreased by 65.6%, 13.5%, and 32.8%, respectively, compared to the same values for PP alone. Fourier transform infrared spectroscopy (FTIR) was used to investigate the changes which accompanied the thermal degradation of the polymer containing PHYPI. Changes in the infrared spectra for the polymer undergoing degradation indicate that structures containing C=C and P-N-C were formed as a consequence of the presence of PHYPI. These transformations enhanced char formation to provide condensed phase protective action. At the same time, non-combustion volatile gases such as water and carbon dioxide may be released to dilute the fuel load in the gas phase. All evidences illustrate that PHYPI is an effective flame retardant for PP.

Herein, B, P co-doped porous carbon (PC BP ) was prepared from K 2 B 4 O 7 and phytic acid-modified cellulose via chemical activation and used as electrode materials for supercapacitors. Of which, K 2 B 4 O 7 not only acts as a source of boron, but also as an activation agent in the process of activation. The electrochemical properties of porous carbon materials were significantly improved by doping P and B. Compared with the porous carbon doped by B, PC BP shows almost higher specific capacitance and better rate performance. When evaluated as supercapacitor electrode materials in 6 M KOH electrolyte under two-electrode test systems, the as-prepared PC BP exhibits an excellent electrochemical performance: a high specific capacitance of 214 F g −1 at 0.05 A g −1 , a good rate capability of 142 F g −1 at 20 A g −1 and 2.7% capacitance loss after 10,000 cycles. Thus, the co-doping of B and P holds great promise for improving the specific capacitance and rate capability, which is attributed to the synergistic effect of B and P co-doped. Graphical abstract

MXenes, with their metallic conductivity and complex surface chemistry, are emerging as promising newcomers in the field of energy storage materials. In this work, we present innovative iterations of MXene synthesised by phytic acid selective etching and self-assembly, denoted P-MXene, with phytic acid adhered tightly to the surface and increased the interlayer spacing of the MXene, which was beneficial to the embedment/desorption of K + , and etched more active sites. When used as an anode material for potassium ion batteries, P-MXene exhibits superior specific capacity of 135 mAh*g −1 , long-term cycling stability capacity of 128.8 mAh*g −1 and higher rate performance (the final capacity of 110.0 mAh*g −1 ). This transformative development not only establishes a new paradigm for MXene derivatives, but also paves the way for the exploration of high-performance MXene-based energy storage materials.
