High Radiation-Resistant Elastomer via Constructing Radiation-Stable Macromolecular Network

ACS Macro Letters, Journal Year: 2025, Volume and Issue: unknown, P. 405 - 412

Published: March 17, 2025

The high-energy radiation in nuclear energy, space missions, and other radiation-related fields would accelerate the deterioration of polymers, greatly reducing their service life reliability. Here, a new concept resistance has been proposed, which is to reduce effect degradation on polymer properties by constructing radiation-stable macromolecular network. Concretely, this strategy was achieved introducing stable coordination interaction between macromolecules, radiation-resistant elastomers (PG-Zn) were prepared. In radiated PG-Zn, intermolecular could maintain chain network well, even though its main undergone chain-breaking reaction. Therefore, after 300 kGy irradiation, PG-Zn still maintained nearly 18 MPa strength 650% elongation at break, tensile deformation hysteresis rate almost unchanged. be further modified, modified elastomer retains more than 80% mechanical radiation, most reported date. addition, design good scalability used prepare sensors, showing three times ordinary group under irradiation. This presented novel promising approach for solving radiation-aging problem polymers.

Polypropylene reinforced with hollow glass microspheres: effect of thermal aging and reprocessing

Polímeros, Journal Year: 2025, Volume and Issue: 35(1)

Published: Jan. 1, 2025

Abstract The hollow glass microspheres (HGM), exhibit low density, reduced dielectric constant, and good thermal conductivity. This study assessed the mechanical performance of polypropylene (PP) reinforced with HGM under artificial aging conditions. compositions underwent two rounds reprocessing in a single-screw extruder, samples were prepared for both tensile impact testing. Tensile specimens subjected to at 100 ºC seven 21 days. Mechanical tests carried out on before after aging, while exposed visual inspection, optical microscopy, Fourier transform infrared spectroscopy analysis. Visual inspection microscopy revealed improved PP-HGM interaction due additives, no deformation or damage from reprocessing. Infrared showed minor degradation PP structure post-exposure. In summary, presence content HGM, reprocessing, time significantly affect properties (elastic modulus, breaking stress, elongation break, resistance).

Accelerated Aging Method of Performance Attenuation of Crystalline Silicon Photovoltaic Modules Under Full-Spectrum Conditions

Materials, Journal Year: 2025, Volume and Issue: 18(7), P. 1507 - 1507

Published: March 27, 2025

Crystalline silicon photovoltaic modules, when subjected to diverse environmental conditions, undergo progressive performance degradation due factors such as temperature, humidity, light irradiation, and operational duration. Understanding this is essential for reliably correlating laboratory tests with actual performance. This study examines the reduction in power generation capacity resulting from prolonged interaction of these modules various factors. We developed an accelerated aging model that simulates real-world conditions lab, using multiple doses factors, full-spectrum varying intensities. The indicates acceleration factor 143.36, though might be higher conditions. To validate our model, we conducted a series under controlled specifically at temperature 70 °C, humidity level 60%, triple standard incident intensity. findings revealed significant correlation between long-term observed 8-10 years. For polycrystalline correction coefficient associated method was determined range 0.3 0.5. presents reliable approach connecting projections testing, providing critical insights into reliability patterns crystalline within industry.

High-Energy Electron Beam-Induced Enhanced Thermoelectric Performance and Irradiation Resistance of PEDOT: PSS

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: May 20, 2025

Electron beam (EB) irradiation, a powerful method for electronic and molecular structure regulation of polymer materials, has been proven to be an effective strategy boost the electrical conductivity (σ) PEDOT: PSS. However, irradiation damage from chain scission cross-linking adverse effect on mechanical thermal performance. Herein, we propose convenient approach enhance resistance property by adding chemical oxidant, ammonium persulfate (APS), into PSS, in which irradiation-induced fragmentations can reaggregated via initiating free radical polymerization through APS. The PSS films doped with 5 wt % APS were exposed 10 MeV EB at doses ranging 2.5 20 kGy. PSS-APS reached 596 S cm-1 dose kGy, 2 orders magnitude higher than that pure (4.94 cm-1), while Seebeck coefficient remained nearly constant. An optimal thermoelectric power factor (PF) 16.75 μW m-1 K-2 was achieved. 1000-fold increase carrier concentration (n) elucidate enhancement PF despite deterioration mobility. During more occurred Structural characterization DFT computational results implied imine or protonated amine brought could not only improve but also narrow band gap, helped charge transport. fragments caused during polymerized new chains, influenced transportation carriers resulted enhanced stability properties films. This work provides simple innovative treatment both conducting polymers.

Since their inception, plastics have become indispensable materials. However, used for extended periods in industrial applications are prone to aging, which negatively impacts material behavior and performance. To ensure the long-term usability of these materials, they must be tested real-time, in-service environments assess degradation. In practice, however, accelerated aging techniques commonly employed avoid time loss. Over time, various indicators degradation emerge, such as changes molecular weight, cracking, mechanical properties like strain at break impact strength.
