Two natural plasticizers derived from cardanol (CD), cardanol acetate (CA) and epoxidized cardanol acetate (ECA), were synthesized and characterized by 1 H NMR and 13 C NMR. The plasticizing effects of the obtained plasticizers on semi-rigid polyvinylchloride (PVC) formulations were also investigated. Two commercial phthalate ester plasticizers, dioctyl terephthalate (DOTP) and diisononyl phthalate (DINP), were used as controls. Mechanical and thermal properties, compatibility, thermal stability, microstructure, and workability were assessed by dynamic mechanical analysis (DMA), mechanical analysis, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and dynamic stability analysis, respectively. Results indicated that the natural plasticizer ECA had overallsuperior flexibility, compatibility, thermal stability, and workability comparable to both controls. The obtained CA and ECA have lower volatility resistance and similar extraction and exudation resistance than that of DOTP and DINP. The CA was further blended with DOTP in soft PVC films. Results of DMA, TGA and mechanicalanalysis indicated that CA can serve as a secondary plasticizer to improve the related properties of soft PVC formulations. These CD derived plasticizers show promise as an alternative to fully or partially replace petroleum-based plasticizers.

To prepare a new type of composite membrane with high flux and good dye removal performance, hyperbranched polyester (HPE) was selected as the reactive macromonomer and a cross-linked HPE skin layer was successfully formed on the PVC-UF membrane via one-step acteal reaction between HPE and glutaraldehyde (GA) from aqueous emulsion. The resultant membranes were characterized using ATR-FTIR, FESEM , surface zeta potential and CA, while the effects of GA concentration and heat treatment time on their performance were evaluated by permeate flux and rejection rate of sunset yellow (SY). The obtained HPE-M5 membrane exhibited a SY rejection rate of 96.4% and a permeate flux of 237.6 L m − 2 h − 1 at 0.4 MPa. Due to the good stability and the feasibility of backwashing treatment, the prepared composite hollow fiber membrane has a promising perspective of application in dye removal.

Developing effective technologies for extraction of Li + from salt-lake brines with high Mg 2+ /Li + ratios is paramount for sustainable utilization of lithium resources in electric vehicle and nuclear energy industries. In this work, hybrid membranes were prepared with polyvinyl chloride matrix and six metal−organic frameworks (MOFs@PVC) to separate Li + from Mg 2+ in solution. The effects of pore size sieving and sulfonation of the MOFs on the Li + /Mg 2+ separation efficiency were evaluated using the current-voltage ( I – V ) method, and the stability of the MOFs@PVC membranes was systematically evaluated. The loading amount of MOFs and the thickness of the membranes were also optimized for Li + transport and selectivity. The results show that the small pore size and sulfonation of MOFs are benefit to separate Li + from Mg 2+ . Specifically, PVC-based hybrid membrane containing HSO 3 -UiO-66 shows the highest selectivity for Li + (Li + /Mg 2+ > 4), with the diffusion coefficient of 2.0×10 -10 cm 2 s -1 for Li + and 4.67×10 -11 cm 2 s -1 for Mg 2+ . This study highlights the stable sulfonated Zr-based MOF with suitable pore sizes for membrane-based Li + /Mg 2+ separation, and provides a potential alternative for recovering lithium from salt-lake brines.

The exposure of micro- and nanoplastics (MNPs) via medical device is still unknown to us. Herein, a visual quantitative detection of polyvinyl chloride (PVC) MPs and a fluorescent quantitative detection of PVC NPs were developed. To overcome the aggregation of PVC NPs, sodium dodecylbenzene sulfonate was used as the stabilizer of PVC NPs. The brand-new disposable PVC infusion tubes were found to carry PVC MPs with the average total number (ATN) of 931.4 particles and PVC NPs with the average mass of 0.040 μg, respectively. For four typical infusion fluids such as 0.9% sodium chloride, 5% glucose, 5% sodium bicarbonate , hydroxyethyl starch 40 sodium chloride, the released PVC MPs and NPs were ranged from 1003.6 ∼ 3494.6 particles and 0.042 ∼ 0.087 μg, respectively in stimulating normal infusion scenario (room temperature 4 h). The released PVC MPs and NPs were also increased with the infusion duration and temperature. The released PVC MPs are mainly in granular form, accounting for 38 ∼ 49% of the total PVC MPs. Our findings indicate PVC MNPs can enter the blood vessel directly with the infusion fluids during intravenous infusion and the PVC MNPs exposure risk towards patients deserves more attention.

A tung-oil-derived renewable plasticizer, tung-maleic triglycidyl esters (TMTE), was prepared and incorporated into poly(vinyl chloride) (PVC) for the first time. The chemical structure was studied by Fourier transform infrared (FTIR), 1H nuclear magnetic resonance (NMR), and 13C NMR. The plasticizing effects of TMTE replacement of dioctyl phthalate (DOP) in soft PVC films were researched. Thermal stability, thermal degradation performance, dynamic mechanical property, and mechanical properties of pure PVC and PVC films were investigated with thermogravimetric analysis (TGA), TGA-FTIR, TGA-mass spectrometry, dynamic mechanical analysis, and mechanical test. The results showed that PVC films plasticized with the TMTE exhibited increased thermal stability, plasticizing effect, compatibility, and flexibility. When 30 phr (parts per hundred parts of resin) DOP was substituted with TMTE in PVC blends, glass transition temperature (Tg) dropped from 41.46 to 40.18 °C, the initial decomposition temperature (Ti), 10% and 50% mass loss temperatures (T10 and T50), had maximum increases of 8.0, 20.0, and 27.5 °C, respectively. The interaction between TMTE and PVC molecule was also discussed. Furthermore, the extraction, exudation, and volatility resistance of plasticizers were carried out and analyzed by solubility parameters, the results of which revealed the migration stabilities of PVC films were promoted with the increasing amount of TMTE.

Electrochemically upcycling polyvinyl chloride (PVC) into high-value small molecules represents a sustainable strategy for mitigating plastic pollution. Herein, a cost-effective self-supporting electrode with abundant vacancies, i.e. , NiFe-layered double hydroxide nanoarrays in-situ grown on the surface of carbon paper (denoted as NiFe V -LDH/CP), is developed for the electro-Fenton degradation of PVC microplastics (MPs). The NiFe V -LDH catalyst shows a high selectivity of 76 % towards H 2 O 2 production via two-electron oxygen reduction reaction (2e - ORR). Density functional theory (DFT) calculations reveal that the energy barrier of rate-determining step (*H 2 O 2 desorption) decreases over the vacancy-enriched NiFe V -LDH related to the pristine NiFeZn-LDH. The influence of vacancy concentration, reaction temperature and initial concentration of PVC MPs were systematically investigated. Under optimized conditions, the NiFe V -LDH/CP electrode exhibits an outstanding degradation performance of PVC MPs via direct cathodic reduction and oxidation by hydroxyl radicals. This work demonstrates that the electro-Fenton technology using LDH-based self-supporting electrodes is a promising and environmentally-friendly approach for waste plastic treatment.

In the present study, hexagonal boron nitride (h-BN) nanosheets were first functionalized with hydroxyl groups (h-BN-OH), and then phosphonic acid groups were grafted onto the h-BN surface (BNP) using aminotris(methylenephosphonic acid) (ATMP) through a condensation reaction. The BNP was then incorporated into a polyvinyl chloride (PVC) matrix to prepare PVC/BNP composites. Thermogravimetric analysis showed an increase in thermal stability, with BNP/PVC composites exhibiting greater resistance to degradation at elevated temperatures. The addition of BNP improved the dispersion and interfacial adhesion within the PVC matrix, as confirmed by Scanning Electron Microscopy (SEM). Furthermore, the PVC/BNP composites exhibited a 22.5% increase in tensile strength (21.2 MPa) and an 82% improvement in elongation at break (464%) compared to pristine PVC composites, which showed a tensile strength of 17.3 MPa and an elongation at break of 255%. Moreover, the addition of BNP notably improved the thermal conductivity from 0.18 to 1.50 W/m K as the BNP content increased from BNP-0 to BNP-4. These improvements in thermal stability and mechanical strength, as well as excellent migration resistance, make BNP/PVC composites highly promising for advanced applications.

Polyvinyl Chloride (PVC) is widely utilized across various industries due to its outstanding comprehensive properties. However, the current reliance on harmful petroleum-based plasticizers, such as phthalates (PAEs), in PVC film processing poses significant environmental and health concerns, limiting its applications. To address this issue, we developed epoxidized isosorbide oleate (EIOA), a non-toxic, bio-based plasticizer with excellent plasticizing performance, as a sustainable alternative to conventional petroleum-derived plasticizers. EIOA was synthesized via esterification and epoxidation reactions using bio-derived raw materials, including isosorbide and oleic acid. When compared to the commercially available plasticizer di(2-ethylhexyl) terephthalate (DOTP), EIOA-plasticized PVC demonstrated superior performance, including: non-toxicity, high optical clarity (87% light transmittance), enhanced thermal stability (T50% was 70 °C higher than pure PVC), exceptional flexibility (~636.5% elongation at break), superior migration resistance (only 1.8% migration in n-hexane and 0.4% in ligroin), and improved compatibility with PVC. Therefore, EIOA-plasticized PVC is highly suitable for medical devices, food packaging, and other applications requiring direct human contact, eliminating safety concerns associated with traditional plasticizers.

The ever-increasing prevalence of microplastics and different bisphenols made the presence of bisphenol-attached microplastics a critical concern. In this study, experiments were performed to examine desorption behaviors and cytotoxicity performance of contaminated microplastics in aquatic surroundings and intestinal environment after ingestion by organisms (cold-/warm-blooded). The kinetic study shows that the rate of desorption for bisphenols can be enhanced threefold under simulated warm intestinal conditions. The Freundlich isotherms indicate multiple-layer desorption of the bisphenols on the heterogeneous surfaces of polyvinyl chloride (PVC) microplastics. Hysteresis was detected in the adsorption/desorption of bisphenols in a water environment, but no adsorption/desorption hysteresis was observed in the simulated intestinal conditions of warm-blooded organisms. Due to enhanced bioaccessibility, the desorption results imply that the environmental risk of contaminated PVC microplastics may be significantly increased after ingestion at a high bisphenols dosage. Although with different IC 50 , the five bisphenols released under the intestinal conditions of warm-blooded organisms can cause higher proliferation reduction in fish and human cell lines than the bisphenols released in water. This study helps elucidate the consequential fate and potential cytotoxicity of contaminated microplastics and the possible implications of the microplastics as a critical vector for bisphenols to increase the potential health risks.

This study investigates the impact of layered double hydroxides (LDHs) intercalated with various ions on the thermal degradation and stability of polyvinyl chloride (PVC). Three types of LDHs—carbonate LDHs (C-LDHs), diphenyl phosphate LDHs (P-LDHs), and sarcosine LDHs (N-LDHs)—were synthesized using co-precipitation and hydrothermal methods. Thermogravimetric analysis (TGA) revealed that C-LDHs significantly enhanced the thermal stability of PVC, increasing the activation energy during early degradation phases by up to 25% compared to pure PVC. N-LDHs also improved stability, particularly at higher temperatures, with activation energy rising by 18% in the later stages. P-LDHs, however, showed the least stabilization effect, with a 10% lower activation energy compared to pure PVC. The degradation process of PVC in the presence of LDHs was analyzed using model-free methods, which revealed the complex multistep nature of PVC degradation. Reaction mechanisms were predicted using the generalized master plot method, identifying distinct stages of thermal degradation. Overall, C-LDHs were found to be the most effective at retarding PVC thermal degradation, suggesting their potential as advanced eco-friendly stabilizers. The use of model-free methods and reaction mechanism analysis offers new insights into the design of more efficient thermal stabilizers for polymers.

Effective phosphorus recovery in natural aquatic ecosystems necessitates the integration of phosphorus adsorbents with appropriate carrier materials to develop functional devices, thereby addressing the challenge of water eutrophication. In this study, we report for the first time that MgLa layered double hydroxide powder was anchored in situ on polyvinyl chloride substrates (PVC@MgLa-LDH) by solvent exchange method, resulting in the formation of composite films with hydrophilic, lightweight and flexible characteristics. Within a phosphorus solution of 100 mg P /L, the adsorption capacity achieved an impressive 66.5 mg P /g, alongside commendable reusability. Notably, comparative assessments revealed that the adsorption sites of MgLa-LDH slightly affected by the PVC substrate. Given their favorable transport and recovery attributes, PVC@MgLa-LDH composite films show significant potential for application in phosphorus recovery initiatives in open aquatic environments. Additionally, this fabrication method offers a promising framework for the development of customized adsorption films targeting various pollutants.

Novel Ce/TiO2 were synthesized using a solution-based method involving two types of Ce(III)-doped polyoxotitanium cages, namely ([Ti28O38(OEt)38CeCl(EtOH)1.4] and [Ti8O7(OEt)21Ce(EtOH)]). This novel material was used to coat the surface of polyvinylidene chloride (PVDC)/polyvinyl chloride (PVC) film, resulting in a homogeneous CeO2/TiO2@PVDC/PVC film. Remarkably, the CeO2/TiO2@PVDC/PVC film exhibited notable hydrophobicity and UV absorption capacity. Furthermore, the UV absorption capacity of the films was significantly improved with increasing CeO2/TiO2 content. The incorporation of CeO2/TiO2 also led to a substantial improvement in the barrier properties of the film, particularly in terms of water vapor permeability. These modified films hold great potential and offer a wide range of applications in the pharmaceutical packaging and food packaging industries.
