“…To evaluate the thermal stability of the epoxy-based composites, TGA was performed as a function of temperature, and the results are illustrated in Figure a. The TGA curves reveal that the neat epoxy undergoes significant weight loss at around 400 °C, indicating low resistance to thermal decomposition under inert conditions.…”

With the advancement of electronics toward multifunctional, highly integrated, and miniaturized designs, significant heat accumulation has become a critical issue, potentially leading to thermal failure or even explosions. Thus, thermally conductive materials with high dielectric properties have garnered considerable attention in the field of advanced electronics. Polymer-based composites are particularly promising for overcoming this challenge by providing high thermal conductivity with a lower filler content. In this study, we demonstrate a composite consisting of functionalized BN, epoxy, and BNNTs prepared through ultrasonication. This composite exhibits remarkable thermal conductivity, achieving 5.84 W/mK (out-of-plane) and 49.57 W/mK (in-plane) at a 40 wt % filler content. The higher thermal performance of the BNNT(2%) + DNBN/epoxy composite is attributed to several factors: (i) 1D structure of BNNTs creates efficient thermal pathways, facilitating heat transfer within the composite, and (ii) functionalization and strong covalent interactions between DNBN/ epoxy and BNNTs reduce thermal resistance and improve heat transfer efficiency, enhancing overall thermal conductivity. The addition of 2% BNNTs to the DNBN/epoxy composite increases the thermal stability, viscosity, and glass transition temperature (T g ). Moreover, the composite demonstrates excellent dielectric properties, with a dielectric constant of 4.2 and negligible dielectric loss (0.0011) at a 40 wt % filler content. The BNNT(2%) + DNBN/epoxy composite, with its superb thermal conductivity and excellent dielectric properties, offers significant advantages for thermal interface materials in advanced electronic applications, ensuring reliability and performance in increasingly demanding environments.

“…This versatility allows for the incorporation of diverse fillers, a practice that extends the foams' utility by enhancing their intrinsic properties. Among the arsenal of modifiers, flame retardants stand as a vital component, imparting increased fire resistance to these foams [22][23][24]. Different synthetic fibers (e.g., polymers, glass fibers) or natural fillers (e.g., cellulose, chitin, hazelnut and eggshell), on the other hand, reinforce the polyurethane foam's structural integrity [25].…”

With the technological developments witnessed in recent decades, nanotechnology and nanomaterials have found uses in several common applications and products we encounter daily. On the other hand, polyurethane (PU) foams represent an extremely versatile material, being widely recognized for their extensive application possibilities and possessing a multitude of fundamental attributes that enhance their broad usability across various application fields. By combining the versatility of PU with the antimicrobial properties of nanoparticles, this emerging field holds promise for addressing the urgent need for effective antimicrobial materials in various applications. In this comprehensive review, we explore the synthesis methods, properties and applications of these nanocomposite materials, shedding light on their potential role in safeguarding public health and environmental sustainability. The main focus is on PU foams containing metal and metal oxide nanoparticles, but a brief presentation of the progress documented in the last few years regarding other antimicrobial nanomaterials incorporated into such foams is also given within this review in order to obtain a larger image of the possibilities to develop improved PU foams.
