The global scenario on PVC plasticizer is experiencing a drastic change from petroleum-based, toxic di-(2-ethylhexyl) phthalate (DEHP) toward renewable, non-toxic bio-alternatives. However, replacing diisodecyl phthalate (DIDP), a DEHP analogue specifically intended for plasticizing PVC automotive upholstery, with bio-alternative remains a challenge as few bio-plasticizer volatilizes from PVC as slowly as DIDP, a crucial aspect compulsorily required by automotive industry. Here, we demonstrate that covalently attaching two short esters at the α -position of all components of a traditional epoxidized fatty acid methyl ester via a two-step, hydrogen-to-ester nucleophilic substitution in a one-pot procedure yields an epoxidized fatty acid tri-ester bio-plasticizer with remarkably suppressed volatilization from PVC, and hence an extremely low fogging value comparable to DIDP. With this strategy in hand, DIDP, long deemed irreplaceable despite its toxicity and non-renewable nature, may ultimately be phased out. Graphical Abstract

In this work, a novel SERS sensor was obtained by choosing PVC as the carrier, the pre-prepared Ag NPs were dispersed to PVC casting solution though solvent casting method for fabrication of transparent, flexible and tough SERS substrate (Ag NPs/PVC membrane, APM). Meanwhile, considering the complexity of actual detection environment, the APM surface was covered with imprinted layer by using atom transfer radical polymerization to form the specific recognition sites of target analyte on the membrane surface to achieve the selective detection of norfloxacin. Worth mentioning at this work was the SERS-MIMs sensor (APM-MIMs) we obtained can realize undifferentiated detection either top or bottom sides, which relative standard deviation (RSD) were 12.1% and 5.9% respectively. Sensitive detection of norfloxacin was achieved on the scale of 10 −5 to 10 −9 M in standard solutions, which SERS intensity at 1595 cm −1 revealed excellent linear relationship with solution concentration, and the correlation coefficient was 0.9986. The APM-MIMs prepared by simple methods could be used as a potential SERS substrate to detect trace substances.

Discarded PVC/cotton waterproof materials pose a significant challenge for sustainable recycling due to the release of corrosive HCl and the formation of sintered carbonaceous residues during conventional thermal processing. Here, we report a synergistic catalytic strategy for the co-conversion of PVC/cotton-based waste into value-added chemicals under mild hydrothermal conditions. Initially, Ru/TiO 2 catalyzes the dehydrochlorination of PVC at 190 ° C; the In Situ-generated HCl serves as a Brønsted acid catalyst to hydrolyze cellulose to glucose, followed by hydrogenation to sorbitol in 61.4% yield. The resulting dehydrochlorinated PVC residue undergoes oxidative aromatization to yield aromatic carboxylic acid, with a liquid product yield of 19.5% and a phthalic acid selectivity of 63.7%. Density functional theory calculations attribute the efficient dechlorination to Ru(1015) sites, which lower the activation energy for HCl elimination by 18.76 kJ mol −1 . This catalytic system demonstrates tolerance toward real-world waste composite materials and establishes a novel pathway for the integrated upcycling of halogenated plastics and lignocellulosic biomass. Life-cycle assessment shows 97% lower global warming potential than incineration, advancing resource circularity and sustainable waste management.

Brittleness and low fracture toughness severely limit the performance of rigid polyvinyl chloride (PVC) composites in extreme environments. To address this, we developed a modified filler (mATP@PMMA) by first modifying attapulgite (ATP) with a titanate coupling agent (TCA), which then served as a molecular bridge to graft polymethyl methacrylate (PMMA) onto the ATP surface via emulsion polymerization. This design promotes uniform dispersion and strong interfacial adhesion, effectively dissipating energy and thereby enhancing mechanical properties. Experimental results show that adding only 3 phr of mATP@PMMA significantly improves the processability, thermal stability, and dynamic mechanical performance of the PVC composite. At room temperature, tensile strength, flexural strength, and impact strength increase by 26.8%, 32.5%, and 23.1%, respectively. Even at −20 °C, the composite maintained high strength and exhibited considerable resilience, with SEM fractography clearly revealing effective interfacial interactions. While the impact strength of PVC drops by 48.4% at low temperature, the composite with PVC/mATP@PMMA shows only a 14.8% reduction. As a highly efficient performance additive, mATP@PMMA demonstrates considerable potential for manufacturing high performance composites.

Ultrasound detection and acoustic imaging technologies have broad applications in biomedical diagnostics, flexible wearable devices, and human-machine interaction. Conventional inorganic piezoelectric ceramics exhibit high acoustic impedance and large mechanical rigidity. This results in poor impedance matching not only with propagation media such as water but also with soft biological tissues, leading to significant energy reflection, scattering, and signal distortion. To address these limitations, we developed polymer/organic-inorganic hybrid metal halide composite films and devices, using TMCM-CdCl3 MRs (TMCM = trimethylchloromethyl ammonium; MRs = microrods) as fillers and poly(vinyl chloride) (PVC) as the matrix. Strong interactions between PVC and the one-dimensional hybrid perovskite lead to a highly coupled micro-scale interface, while the polymer’s inherent flexibility and the composite’s low acoustic impedance suppress reflection and scattering, enabling high-fidelity signal transmission. Devices based on TMCM-CdCl3 MRs/PVC demonstrate superior ultrasound detection performance compared to conventional PVDF and PZT materials. At 10 MHz, the composite films maintain a frequency-domain signal fidelity of 74.1% (corresponding to a time-domain fidelity of 91.2%), with output comparable to commercial PZT devices. Additionally, the devices exhibit excellent piezoelectric energy harvesting capability and can accurately sense various human motions. These results highlight the significant potential of metal halide/polymer piezoelectric composites for advanced ultrasound sensing and energy harvesting applications.

A series of bio-based 2,5-thiophenedicarboxylates were successfully synthesized, and their chemical structures were characterized using Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (NMR). The influence of alkyl chain length and branching on the plasticizing properties of 2,5-thiophenedicarboxylates in poly(vinyl chloride) (PVC) was evaluated through dynamic mechanical analysis (DMA), hardness measurements, and tensile testing. It was found that the plasticizing efficiency of 2,5-thiophenedicarboxylates decreased as the alkyl chain length increased, as reflected by the gradual increase in glass transition temperature ( T g ), hardness, and elastic modulus. Additionally, among 2,5-thiophenedicarboxylate isomers with the same molecular weight, those with branched alkyl chains exhibited superior plasticizing efficiency compared to those with linear alkyl chains. The above results suggested that optimizing alkyl chain length and branching could further improve the plasticizing efficiency of 2,5-thiophenedicarboxylate plasticizers in PVC. Notably, 2,5-thiophenedicarboxylates showed greater polarity and improved migration resistance in non-polar solvents than commercial dioctyl phthalate (DOP), suggesting their potential application in PVC products exposed to non-polar environments.

Thermal stabilizers play a crucial role in improving the thermal stability of PVC samples. However, the effect of thermal behavior of the stabilizer itself on PVC samples has been rarely reported. In this work, a metal organic framework Zn–Atz with a spatial three-dimensional structure was prepared and applied for stabilizing PVC. It was found that Zn–Atz displays both initial and long-term thermal stabilization effects on PVC. However, its long-term thermal stabilization effect is unsatisfactory due to the hydrogen chloride and unstable chlorine atom diffusion rate limitation in the pore structure of Zn–Atz. CaSt2 and triphenyl phosphite (TP) can quickly absorb hydrogen chloride and chlorine free radicals produced in the PVC thermal degradation. When utilized together with Zn–Atz, CaSt2 and TP can provide longer reaction time for the diffusion of hydrogen chloride and unstable chlorine atoms in the pore structure of Zn–Atz, to significantly improve the long-term thermal stability of PVC. Meanwhile, a possible synergistic stabilization mechanism of Zn–Atz, CaSt2 and TP was proposed.

A synthetic approach for the preparation and conductive polyurethane (PU)/activated carbon (AC) microcapsule to poly(vinyl chloride) (PVC) is described. The developed flexible PVC/PU/AC microcapsule composites are economically and ecologically viable, because it is based on AC as inexpensive starting material; the reactions can be carried out one-pot with quantitative yields of the PU/AC microcapsule. The approach is furthermore highly versatile and allows for the preparation of excellent plasticiser migration stability, electrical property and mechanical properties that may be adjusted to a broad range of applications from highly flexible to semi-rigid PVC.

To develop an efficient and green adsorbent for cationic dye removal, a one-step method was developed to prepare the IFPHC adsorbent, involving the solvent-free radical copolymerization of itaconic acid with a bamboo/PVC co-hydrothermal carbon. The reaction was initiated by ammonium persulfate under alkaline conditions. The performance of the resulting IFPHC was assessed for its efficacy in removing methylene blue (MB) from water, demonstrating a high adsorption capacity. Characterization results from Zeta potential, BET, FTIR, XPS, and SEM demonstrated a high density of carboxylate functional groups on the material, accounting for its high affinity for cationic pollutants. As determined by the Langmuir model, IFPHC exhibited a maximum MB adsorption capacity of 613.94 mg·g⁻¹ at 298 K. The adsorption behavior was accurately captured by the Langmuir isotherm and pseudo-second-order kinetics, suggesting a monolayer chemisorption process. Combined characterization analysis confirmed that electrostatic attraction and hydrogen bonding were the primary mechanisms. The former occurred between IFPHC's anionic groups and MB's cationic –N(CH₃)₂⁺ moiety, while the latter involved IFPHC's C–OH/carboxylate groups and the N atom in MB's phenothiazine ring. Therefore, this work demonstrates that solvent-free radical copolymerization provides a green and practical alternative to conventional solvent-based methods for fabricating functional hydrochar. It simultaneously addresses the valorization of PVC-containing waste and the remediation of dye-laden wastewater, presenting a novel strategy that fills the gap for scalable and sustainable adsorbent synthesis.

As a widely used polymer additive, polyvinyl chloride (PVC) plasticizers can significantly improve the thermal processing performance and flexibility of PVC. However, commercially available low-molecular-weight plasticizers suffer from poor migration resistance, leading to material failure due to plasticizer migration during long-term usage. In this work, a series of polyesters with long side-chain, poly(OGE-PO-PA) (PGEPE), were successfully synthesized by ring-opening copolymerization of octyl/decyl glycidyl ether (GE), propylene oxide (PO) and phthalic anhydride (PA) for the purpose of plasticizing PVC. The influence of molecular weight and long-branch density on the plasticizing performance was investigated. Results demonstrated that PGEPE-60-3 k, with a long side chain content of 60 % and a molecular weight of 3.0 kg/mol, exhibited most effective plasticizing properties. The plasticized PVC with 30 phr PGEPE-60-3 k plasticizer displayed the optimal mechanical performance with tensile strength of 39.6 MPa and elongation at break of 196 %. Furthermore, it showed high optical transparency and outstanding migration resistance in both polar and non-polar solvents. Mass loss remained minimal, ranging from 0.36 % in 15 % ethanol to 0.93 % in cyclohexane, confirming its excellent stability under various conditions.

A method for predicting the thermal stability effect from the structure of thermal stabilizers could greatly accelerate the research of efficient thermal stabilizers and achieve the high performance of the PVC products. In this work, the Gaussian software was used to establish the method by calculating the binding energy and the electron distribution value (NPA charge) of the thermal stabilizers. Three initial-type [Zn(Bzo) 2 , Zn(PTBBA) 2 , and Zn(PNBA) 2 ] and three long-term [Zn(Pro) 2 , Zn(Ple) 2 , and ZCR] organic zinc thermal stabilizers were used to establish quantitative relationships between the binding energy and the NPA charge with the thermal stability properties of PVC samples. The binding energy of anion and cation could effectively explain the ability of the thermal stabilizers to replace the labile chlorine atoms on the PVC chains and the initial whiteness of PVC samples. Zn(PNBA) 2 with a Zn-O binding energy of 0.134 ha had an initial whiteness retention time of 40 min and a Congo red thermal stability time of 17.2 min on PVC. Moreover, the NPA charge of nitrogen atom could demonstrate the ability of thermal stabilizers to absorb HCl. The higher the NPA charge, the better the ability of absorbing HCl. The NPA charge of nitrogen atom in ZCR reached -1.43 e, resulting in the Congo red thermal stability time of 56.9 min and the long-term thermal stability time of 180 min. Thus, the initial whiteness retention time, long-term thermal stability time, and Congo red thermal stability time of the thermal stabilizers could be quantitatively predicted by combining the binding energy and the NPA charge of nitrogen atom. Moreover, the relationship was verified by the replacement test and absorbing HCl experiment.

Plasticizers that enable flexible polyvinyl chloride (PVC) are usually combustible, restricting the application of PVC in fire-prone scenarios. In this context, intrinsically flame-retardant plasticizers displaying dual function continue to be the focus of intensive research. Despite their efficiency, the majority of these dual-functional plasticizers previously reported contain halogen elements, which, once ignited, emanate toxic and potentially carcinogenic substances, along with toxic gases and smoke, polluting the environment, damaging the biota, and threatening human health. Here, we report a strategy to obtain a halogen-free, intrinsically flame-retardant PVC bio-plasticizer that harnesses the phenolic hydroxyl of naturally occurring cardanol and covalent attachment of an organophosphate moiety. When combined with di-(2-ethylhexyl) phthalate (DOP), the organophosphate-containing cardanol is qualified as a co-plasticizer, while endowing the PVC materials with flame retardancy. Unlike inorganic flame-retardants, the engineered cardanol is compatible with PVC such that the mechanical properties of the PVC materials are not compromised. The rationale underlying the present effort may provide guidance for developing sustainable alternatives to halogen-containing plasticizers to address the sustainability challenge now confronting PVC industry.
