“…Li et al have also shown that the use of combined fillers can improve thermal conductance, in comparison with untreated carbon fiber fillers [ 66 ]. The spray drying method was used to attach spherical aluminum particles to the carbon fibers, reducing the interface thermal resistance of silicone rubber nanocomposites.…”

A Review of Multiple Scale Fibrous and Composite Systems for Heating Applications

Different types of heating systems have been developed lately, representing a growing interest in both the academic and industrial sectors. Based on the Joule effect, fibrous structures can produce heat once an electrical current is passed, whereby different approaches have been followed. For that purpose, materials with electrical and thermal conductivity have been explored, such as carbon-based nanomaterials, metallic nanostructures, intrinsically conducting polymers, fibers or hybrids. We review the usage of these emerging nanomaterials at the nanoscale and processed up to the macroscale to create heaters. In addition to fibrous systems, the creation of composite systems for electrical and thermal conductivity enhancement has also been highly studied. Different techniques can be used to create thin film heaters or heating textiles, as opposed to the conventional textile technologies. The combination of nanoscale and microscale materials gives the best heating performances, and some applications have already been proven, even though some effort is still needed to reach the industry level.

“…A designed structure was achieved through the addition of combined fillers, resulting in a reduced interface thermal resistance of composites. Additionally, hybrid fillers are composed of different sizes, and they complement each other to form a better thermal network, resulting in a thermal conductivity improvement [ 66 ].…”

“…% of thermally conductive filler is used [13]. In addition, in some cases, the use of different sizes (µ and nano) of filler materials has been reported [14]. In this study, three combinations of composites were prepared that are referred to as µ-AlN/n-AlN/PSA, Si-µ-AlN/n-AlN/PSA, and Si-µ-AlN/PSA (Table 1).…”

Acrylic Pressure-Sensitive Adhesive Reinforced with Aluminum Nitride and Its Thermal Properties: Effect of Surface Treatment and Particle Size

2020

Thermal interface materials (TIMs) are very crucial for better heat-transfer in electronics working as an interfacial connection between heat generators and heat sinks. This study is focused on the pressure-sensitive acrylic adhesive tape reinforced with micron-sized and nano-sized aluminum nitride (AlN) particles where the surface modification of AlN particles is done using (3-Aminopropyl) triethoxysilane (3-APTES). The physicochemical analysis of the silanized AlN particles is done using FTIR spectroscopy and scanning electron microscopy (SEM). Furthermore, thermal properties along with thermal conductivity and thermal diffusion are also studied. The main outcome of this study shows that the sample containing surface-treated AlN particles exhibits better thermal conductivity than that of the samples containing µ and nano-sized of AlN due to the comparatively better interactions with the matrix.

“…Os relatos da literatura [14][15][16][17] mostram que algumas cargas, quando incorporadas a matrizes poliméricas, permitem, por exemplo, aumentar sua resistência mecânica [14], proporcionar condutividade térmica [15], elétrica [16] e capacidade de barreira a gases [17]. Porém, para que o compósito apresente melhoria nas propriedades da fase matriz, é necessário que ocorra afinidade físico-química entre a fase matriz e a fase dispersa (carga), além de apresentar morfologia com dispersão homogênea das cargas na matriz [18] .…”
