However, its high insulation characteristics due to the non‐polar structure limit its further applications. This paper introduces the blending of specific antistatic agents, polyamide type antistatic agent (ABS‐2MP), and polyether type antistatic agent (JL‐AS‐55) with ABS. The influence of the presence of the antistatic agent, monomer ratio of styrene (ST) and acrylonitrile in ABS resin, and the rubber content is demonstrated, and finally a high‐impact resistant ABS resin with excellent antistatic properties is obtained. As a result, the hydrophilicity and corresponding antistatic properties of ABS resin were improved by using a higher proportion of ST monomers. With 20% antistatic agent and 24 phr rubber, the resin showed the best antistatic effect. The addition of polyamide 6 further improved the tensile strength and antistatic properties of the resulting material. This research serves to improve and balance the mechanical properties and antistatic properties of ABS resins, overcome the inherent defects, and provide a comprehensive method to broaden the application scope of ABS, which has a vital role in various industrial applications. Highlights High‐impact ABS resin with excellent antistatic properties was prepared. The effect of resin composition on the antistatic properties was studied.

Thermally conductive polymer composites are gaining more attention as the potential next‐generation thermal conductive materials. However, challenges remain, especially the low thermal conductivity (TC) of conventional polymers, which limits their use in devices needing efficient heat dissipation. This paper presents the preparation of Polyamide 6 (PA6) particles coated with graphite to significantly enhance TC by constructing segregated filler networks, using soybean oil epoxide (ESO) as the binder. When the mass ratio of PA6 to ESO is 8:1 and the graphite content is 25 wt%, the TC of the PA6/graphite composite reaches 4.78 W/m K, which is 14 times higher than that of pure PA6. The significant enhancement is attributed to the introduction of graphite and ESO, which improves the graphite coverage on the surface of PA6 particles, thereby establishing a more effective three‐dimensional segregated TC network. Moreover, during the compression molding process, the epoxy groups in ESO react with the amino and carboxyl groups on PA6, preventing ESO from forming a separate phase within the composite and improving the compatibility of the material. This study provides new insights into high TC composites. Highlights Graphite and ESO create a segregated filler network for better heat transfer. Enhancing thermal conductivity compared to the original PA6. Maintaining excellent processing and mechanical properties.","PeriodicalId":20281,"journal":{"name":"Polymer Engineering and Science","volume":"65 5","pages":"2769-2781"},"PeriodicalIF":0.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147332795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the friction‐induced electrostatic charge accumulation occurs easily due to its high resistivity. In this paper, dimethyl octadecyl hydroxy ethyl ammonium nitrate (SN) intercalated reduced graphene oxide (SN‐RGO) were prepared as the conductive agent. The antistatic slow rebound polyurethane foam (ASR‐PUF) was prepared with SN‐RGO/carbon black as antistatic system and silicone‐modified polyethylene glycol (Si‐APEG) as low temperature resistant agent. The structures of SN‐RGO were investigated by Fourier transform infrared spectra (FT‐IR), wide‐angle X‐ray diffraction (WAXD), and scanning electron microscope (SEM), respectively. The effects SN‐RGO on the structures, mechanical properties, low‐temperature resistance, and antistatic property of ASR‐PUF were studied. It was found that SN‐RGO acts as heterogeneous cell nucleating agent, which slightly increases the apparent core density and slightly decreases the porosity of ASR‐PUF. The addition of SN‐RGO increases both the tensile strength and elongation at break of ASR‐PUF, and has little effect on the temperature sensitive index. The surface resistance of ASR‐PUF decreases to 1.1 × 10 8 Ω with a SN‐RGO content of 4 wt%, thereby achieving an antistatic effect. Highlights SN‐RGO acts as heterogeneous cell nucleating agent in PU foaming. SN‐RGO/carbon black provide good antistatic property and mechanical properties without affecting the low‐temperature resistance of ASR‐PUF.

In this study, an imidazolium‐based characteristic was incorporated into the acrylamide‐acrylic acid (AA) system to synthesize a gel with enhanced compressive strength and stability. Firstly, a one‐step method was used to synthesize a bipartite vinyl imidazolium bromide ionic liquid, using N ‐vinyl imidazole and 1,8‐dibromooctane. Secondly, polymer gel microspheres (P(AA‐AM‐ILs)) were designed and synthesized using the microfluidic technique and titration gel method, with acrylamide (AM), AA, and β‐hydroxyethyl methacrylate as raw materials, and potassium persulfate as the initiator. The morphology and structure of the polymer gel microspheres were characterized, and the effects of the ionic liquid cross‐linker content on the water‐absorbing properties and compressive strength of the gel microspheres were investigated. At 800°C, the gel microspheres did not fully decompose, indicating that the material possessed high stability. When the ionic liquid cross‐linker content was 15%, the water absorption ratio reached its highest value at various temperatures, consistently exceeding 3.5 mm mm −1 . Additionally, it exhibited excellent aging resistance, maintaining a compressive strength of 110 kPa after being immersed at 70°C for 120 days, suggesting its suitability for long‐term use.

To tackle this issue, an empirical formula for temperature distribution was developed using Fourier's law as a foundation. The temperature distributions under steady‐state and non‐steady‐state conditions were calculated, simulated, and thoroughly analyzed to evaluate their impact on the foaming quality. The findings reveal that, under both steady‐state and non‐steady‐state conditions, the theoretical temperature calculations demonstrate a consistent decline from the central region to the edge of the isothermal surface, with values ranging between 463 and 311.9 K. The simulation outcomes align closely with the theoretical predictions and demonstrate strong reproducibility. However, uneven temperature distribution caused an initial improvement in foaming quality, followed by subsequent deterioration. Notably, position c (between the center and the edge, near the edge) exhibited the highest foaming quality, achieving a cell density of 7.65 × 10 9 cells/cm 3 and an average cell diameter of 52.5 μm. The relevant research findings offer valuable insights for optimizing the foaming quality of foamed PP materials, providing a theoretical foundation for the design of temperature control systems and the optimization of process parameters in industrial production.
