Flame retardants are prepared by the one-pot method, which is a simple and cost-controlled process. Synergistic action of phosphorus and nitrogen elements provides two-phase flame retardant conditions for combustion in both condensed and gaseous phases. The introduction of cashew phenol groups substantially improves the toughness of epoxy systems.

A novel phosphorus-based compound, (oxybis(4,1-phenylene))bis((2,5-dihydroxyphenyl)(phenyl)phosphine oxide) (ODDPO-HQ), was synthesized and applied to enhance the flame retardancy of epoxy resin (EP). With a phosphorus content of 1.2 wt%, the EP/ODDPO-HQ formulation achieved a vertical burning V-0 grade and a limited oxygen index of 28.9%, while maintaining its thermal stability.

The first section visually represents the preparation of the treated SCF and SGF into PN75 resin to create hybrid composites. The second section showcases the bending and tensile experiments, featuring SEM images of the composite structure and graphs displaying the bending and tensile test results.

Overview of the experimental approach and the key data gathered using ultra small-angle x-ray scattering. High-resolution scattering patterns are collected as the beam passes through the stretched silica-filled rubber compounds. Data from scattering patterns gives insights into the hierarchical structure of the silica filler and deformation-induced cavitation.

The proposed possible interaction model of NaY zeolite, tartaric acid molecules with PVA chains.

Montmorillonite was modified with copper for obtaining clays at different valence states (MtCu²⁺ and MtCu⁰). They were incorporated into PLA films through melt extrusion. The structural, optical, thermal, and mechanical properties of films depended on the valence of clay, where MtCu²⁺ was better dispersed in the polymer matrix and MtCu²⁺/PLA reduced over 2 log₁₀ of Gram+ and Gram− bacterial growth.

Heat treatment-induced surface modification method was used to change the reactive groups on AFs. The number of ester groups greatly increased, which enhanced the reactivity of AFs in epoxy matrix. Meanwhile, the contact angle between AFs and epoxy droplet could be significantly decreased to 54.7°

Mechanism of UF resin modification and synthesis of three-dimensional network structure and comparison of properties of modified UF resin after optimization.

This phase change microcapsule has thermal sensing ability and doping it into silicone rubber can give silicone rubber thermal sensing ability. When the dopant concentration is not greater than 1.5 wt%, the color difference before and after the color change can be up to 37.24. The AC breakdown field strength is increased by 6.92%, and the dielectric properties do not change much, which retains the good electrical properties of silicone rubber, and can be used in large-scale temperature measurement scenarios for electrical equipment.

EP/BTD with enhanced flame retardancy, mechanical properties, and satisfactory transparency were designed and prepared based on a novel bi-DOPO and hydrogen-bonding network.

The transition from polymeric alloy to a micropinned structure of XLPE-PS leads to the development of deeper trapping sites with higher density. As a result, key electrical improvements, such as a remarkable enhancement in DC breakdown strength and a significant reduction in DC conductivity across electric field intervals, are achieved. This advancement leads to the development of reliable composite insulation.
