“…PVDF is an organic polymer known to be resistant to alcohols, oils, strong acids, halogen and basic solutions [38]. PPSU is a heat-resistant polymer with good mechanical and dielectric properties, as well as chemical resistance, usually used to produce membranes for filtration, pervaporation and gas separation [39][40][41]. PEEK is extremely resistant to chemical and thermal degradation.…”

In the evolving landscape of power transformers, the integration of advanced technologies, such as high-performance polymers obtained by Fused Filament Fabrication (FFF), is crucial. This study investigates the compatibility and performance of various 3D-printed polymer materials—Biofila, polyvinylidene fluoride (PVDF), polyphenylene Sulfone (PPSU), polyetheretherketone (PEEK), polyetherimide (ULTEM 1010), and polyetheretherketone reinforced with 20% glass fiber (PEEK-GF20) for use in power transformer components. Through oil compatibility, dielectric strength, and kerosene compatibility evaluations, the study gauges their suitability for this application. The results reveal that PPSU, PEEK, and ULTEM 1010 exhibit promising characteristics, specifically in regard to dielectric breakdown voltage and kerosene and insulating oil compatibility. In contrast, Biofila presented severe cracking when exposed to the mineral oil and PVDF and PEEK-GF20 fall short in terms of dielectric strength, rendering them unsuitable. Kerosene compatibility assessments show minimal material changes, confirming that all studied materials have good resistance to this drying agent, commonly used on power transformers. This research aims to provides essential insights into material selection for a new generation of power transformer parts.

“…Graphene's conductivity can be dynamically adjusted via bias voltage, making it a key element in responsive, tunable devices like switches, tunable filters, and modulators [19][20][21]. A crucial element in our design incorporates Polyphenylsulfone (PPSU), a polymer renowned for its exceptional thermal resilience, making it an optimal dielectric spacer within the graphene layers [22][23][24].…”

In this paper, we introduce a novel nanophotonic multilayer structure comprising graphene, polymer, and PbSe to modulate electromagnetic waves within mid-IR atmospheric windows. Through finite-difference time-domain analysis and micro-genetic algorithms, we achieve a tunable perfect absorber, with optimized control over absorption and emission in the mid-IR range. By adjusting the graphene's chemical potential from 0 eV to 1 eV, we demonstrate a dynamic shift in peak absorptance from 4 µm to 4.22 µm and maintain high absorption at incident angles up to 52 degrees, marking significant advancements in mid-IR radiation management.

The demand for 3D-printed high-performance polymers (HPPs) is on the rise across sectors such as the defense, aerospace, and automotive industries. Polyethyleneimine (PEI) exhibits exceptional mechanical performance, thermal stability, and wear resistance. Herein, six generic and device-independent control parameters, that is, the infill percentage, deposition angle, layer height, travel speed, nozzle temperature, and bed temperature, were quantitatively evaluated for their impact on multiple response metrics related to energy consumption and mechanical strength. The balance between energy consumption and mechanical strength was investigated for the first time, contributing to the sustainability of the PEI material in 3D printing. This is critical considering that HPPs require high temperatures to be built using the 3D printing method. PEI filaments were fabricated and utilized in material extrusion 3D printing of 125 specimens for 25 different experimental runs (five replicates per run). The divergent impacts of the control parameters on the response metrics throughout the experimental course have been reported. The real weight of the samples varies from 1.06 to 1.82 g (71%), the real printing time from 214 to 2841 s (~ 1300%), the ultimate tensile strength from 15.17 up to 80.73 MPa (530%), and the consumed energy from 0.094 to 1.44 MJ (1500%). The regression and reduced quadratic equations were validated through confirmation runs (10 additional specimens). These outcomes have excessive engineering and industrial merit in determining the optimum control parameters, ensuring the sustainability of the process, and the desired functionality of the products.
