Summary: A novel polymer blend formulation was developed by adding polyurethane (PU) and sulfonyldiphenol (SDP) to a dinonylnaphthalene sulfonic acid (DNNSA)-doped polyaniline (PANI) matrix. The results showed that the inclusion of PU and SDP remarkably improved the thermal stability of the films, maintaining desirable conductivity levels over a week. This study provides insights into the functionality, optimization, and deployment of these new film types.

Summary: This study reports a strategy to enhance the thermal resistance of silicone resins by introducing zirconium into the main chain. The molecular simulation shows that the introduction of zirconium atoms leads to the formation of high energy zirconium-oxygen bonds, increasing the cross-linking degree and suppressing the formation of cyclic oligomers. The results suggest that this work could provide a systemic experimental and theoretical foundation for thermal properties enhancement through metal atoms incorporation.

Summary: The present study aimed to discover the thermal degradation mechanism of high-temperature-resistant phthalonitrile (PN) foam under an inert gas atmosphere. PN foam was found to involve a three-stage thermal degradation mechanism, with the presence of gas superposition phenomenon due to the trapped decomposition gases in closed cells. This research is of great significance for understanding the thermal degradation behavior of polymer foam and providing guidance for material design.

Summary: Electroactive aniline tetramer-spider silk composite fibers with high conductivity and mechanical strength were successfully developed using a dip coating method. The composite fibers retained the unique reversible relaxation-contraction behavior of spider dragline silks and the color could be controlled by adjusting pH values and voltages. The study provides valuable guidance for developing highly-conductive electrochromic spider silks for use in E-textiles.

Summary: Polymer-clay nanocomposites have been extensively studied for more than a decade due to their various applications, including UV photodegradation of dyes, lithium nanopolymer batteries, and petroleum pipeline corrosion protection. In this study, montmorillonite clay was intercalated into a polymer structure using hexadecyltrimethylammonium bromide. The nanocomposite was characterized in terms of its structural, electrical, and thermal properties, and the effect of photodegradation on the nanocomposite was assessed under sunlight and UV radiation. The results highlighted the excellent barrier properties of the nanocomposite attributed to the clay component.

Summary: In this study, three fluoroalkyl trimethoxysilane (FATMS) additives with different chain lengths were incorporated into a two-component polyurethane clearcoat to improve its hydrophobic durability. The coatings modified with FATMS maintained their surface hydrophobicity under various conditions, but quickly lost it when exposed to both UV irradiation and/or high temperature with water. The results suggest that the FATMS route is more suitable for indoor applications at room temperature.

Summary: Green flame retardants have garnered attention for their environmental friendliness, but current options fall short in achieving high flame retardancy for flammable polymers and maintaining environmental protection. This study takes a two-pronged approach to address flame retardants and the flame-retardant process. An eco-friendly bio-based synergistic flame retardant (PAU), synthesized using phytic acid (PA) and urea (U), is used to create a flame retardant coating that can be directly applied to any surface shape using polydopamine as an adhesive. The resulting EPS-PAU exhibits excellent flame retardancy, smoke suppression, and light weight while only slightly increasing the density.
