Abstract To adapt to the trend of increasing miniaturization and high integration microelectronic equipments, there is a demand for multifunctional thermally conductive (TC) polymeric films combining excellent flame retardancy low dielectric constant ( ε ). date, have been few successes that achieve such performance portfolio in polymer due their different even mutually exclusive governing mechanisms. Herein, we propose trinity strategy creating rationally engineered heterostructure nanoadditive (FG@CuP@ZTC) by situ self-assembly immobilization copper-phenyl phosphonate (CuP) zinc-3, 5-diamino-1,2,4-triazole complex (ZTC) onto fluorinated graphene (FG) surface. Benefiting from synergistic effects FG, CuP, ZTC bionic lay-by-lay (LBL) strategy, as-fabricated waterborne polyurethane (WPU) nanocomposite film with 30 wt% FG@CuP@ZTC exhibits 55.6% improvement limiting oxygen index (LOI), 66.0% 40.5% reductions peak heat release rate total release, respectively, 93.3% increase tensile strength relative pure WPU between ZTC. Moreover, presents thermal conductivity λ ) 12.7 W m −1 K 2.92 at 10 6 Hz. This work provides commercially viable rational design develop high-performance films, which hold great potential as advanced dissipators high-power-density microelectronics.

Abstract Thermal management is a key link in improving energy utilization and preparing insulation materials with excellent performance the core technological issue. Complex irregular pore structures of hinder exploration structure‐property relationships further promotion material performance. Ordered mesoporous silica (OMS) kind porous ordered frameworks. This work elucidates effects architecture on thermal conductivity silica. Herein, two typical OMS, SBA‐15 SBA‐16, characterized by well‐defined distinct spatial orientations are synthesized to study relevance between structure conductivity. Compared 3D cubic 2D hexagonal exhibits anisotropic that restrict both solid gaseous conduction, thereby providing better insulating. Due influence porosity, found decrease strongly increasing size decreasing wall thickness. Moreover, OMS composite aerogels outstanding insulation, mechanical performance, hydrophobicity fabricated through incorporating into cellulose nanofibers (CNF). Consequently, this contributes deeper understanding heat transfer provides an idea for designing OMS‐based materials, advancing their potential applications.

Functional Heteroatom Substituted Hyperbranched Polymers: Recent Developments and Perspectives

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер 17(9), С. 13324 - 13341

Опубликована: Фев. 20, 2025

Heteroatom-substituted hyperbranched polymers (HBPs) have emerged as a versatile class of functional materials, combining the structural merits architectures with unique chemical functionalities imparted by heteroatoms such boron, silicon, phosphorus, sulfur, selenium, and tellurium. These exhibit distinct physicochemical properties, including low viscosity, excellent solubility, high reactivity, tunable functionality, which position them promising candidates for diverse applications. This Review highlights recent advances in heteroatom substituted HBPs, categorizing from element group their (from Group III to VI, well transition rare-earth metals). The pivotal role modulating polymer properties is explored, key applications highlighted across four principal domains: fluorescent flame retardants, stimuli-responsive polymers, modifications. By integrating insights chemistry, materials science, interdisciplinary research, this underscores potential heteroatom-substituted HBPs addressing current material challenges.
