“…Pure SWCNTs, as well as MWCNTs coatings, have been obtained [31][32][33], but the composite or hybrid layers are even more extensively developed as, e.g., CNTs-HAp [13,22,23,[34][35][36][37] or CNTs-graphene oxide [38]. Most frequently, the electrophoretic deposition (EPD) [12,14,[39][40][41], electrocathodic deposition [15,16,20] or chemical vapor deposition (CVD) processes [42] are applied to prepare CNTs coating.…”

Carbon nanotubes are proposed for reinforcement of the hydroxyapatite coatings to improve their adhesion, resistance to mechanical loads, biocompatibility, bioactivity, corrosion resistance, and antibacterial protection. So far, research has shown that all these properties are highly susceptible to the composition and microstructure of coatings. The present research is aimed at studies of multi-wall carbon nanotubes in three different combinations: multi-wall carbon nanotubes layer, bilayer coating composed of multi-wall carbon nanotubes deposited on nanohydroxyapatite deposit, and hybrid coating comprised of simultaneously deposited nanohydroxyapatite, multi-wall carbon nanotubes, nanosilver, and nanocopper. The electrophoretic deposition method was applied for the fabrication of the coatings. Atomic force microscopy, scanning electron microscopy and X-ray electron diffraction spectroscopy, and measurements of water contact angle were applied to study the chemical and phase composition, roughness, adhesion strength and wettability of the coatings. The results show that the pure multi-wall carbon nanotubes layer possesses the best adhesion strength, mechanical properties, and biocompatibility. Such behavior may be attributed to the applied deposition method, resulting in the high hardness of the coating and high adhesion of carbon nanotubes to the substrate. On the other hand, bilayer coating, and hybrid coating demonstrated insufficient properties, which could be the reason for the presence of soft porous hydroxyapatite and some agglomerates of nanometals in prepared coatings.

“…The relative quantitative contributions of the mentioned bands, starting from the band with the lowest B.E., were as follows: 52.2, 20.3, 14.8, 3.7, and 5.3%. Individual bands of O1 s peak were attributed to the following functional groups: the band at 531.3 eV to a double C=O bond, the band at 533.0 eV to various forms of C‐O bonds (i.e., in ether functional groups and alcohols) and the band at 534.6 eV to carboxyl and carbonate functional groups . According to the results of a quantitative analysis, the relative percentage contributions of individual bands were: 18.4, 47.8, and 33.7%.…”

To meet requirements of regenerative medicine, novel biomaterials should either mimic natural tissues or enable multi‐way stimulation of cells. In this study, we prepared two types of hybrids, differing in composition and morphology by decorating CNTs with iron oxide nanoparticles (IONs), and introduced them into the poly(ε‐caprolactone) (PCL) to prepare biocompatible composite films using casting method. The effect of the type of multi‐walled carbon nanotube (MWCNT)/ION hybrid and its content on the composites’ parameters that are important for cell‐biomaterial interaction that is, surface morphology, wettability, surface energy, and mechanical properties, was examined and compared with results obtained for the PCL, PCL/MWCNT and PCL/ION films. Additionally, materials with IONs were characterized in terms of their magnetic properties. Irrespective of the nanoaddition type, CNT‐based films with content of CNTs up to 1 wt% were characterized by similar surface parameters (completely distinguishable from the PCL film). Pristine CNTs were found to improve the tensile strength of the PCL films while IONs caused its reduction. Interestingly, composites containing 1 wt% of the hybrid, with a 1:1 ratio of MWCNTs and IONs, exhibited tensile strength similar to the PCL/CNTs film. Decoration of CNTs with IONs was found to significantly improve the dispersion level of magnetic phase within the polymer. POLYM. COMPOS., 40:E1818–E1830, 2019. © 2018 Society of Plastics Engineers

A review of thermal interface material fabrication method toward enhancing heat dissipation

Summary Thermal interface materials (TIMs) are applied in electronic devices that are involved in heat generation and raising the temperature. The optimization of TIMs is important in heat dissipation to maintain the good performance of devices, low power during operation, and reduced internal damages among small components. The TIMs are inserted between two contact surfaces to enhance thermal conductivity that will reduce the increment of surface temperature in a longer time and facilitates the cooling process with a consistent power supplied to the system with minimum increment. Research on nanomaterials and hybrid materials aims to obtain maximum thermal conductivity and reduce resistance in the devices. However, the suitable fabrication method for achieving good production and performance is still debatable. Therefore, significant fabrication methods have been explored for various materials. This review provides insights into the current work focusing on the materials used in the development of TIMs by various methods. The discussion begins with the introduction of thermal management and the working principles applied in the system. Then, the methods applied for material fabrication into TIMs, including the advantages and disadvantages of the methods, are discussed. Last, the current challenges and opportunities in methods used are discussed to offer new inputs and improvement in method modification for TIMs design. The targeted thermal performance for the industrial market of TIMs for nanomaterial applications is approximately 100 W/mK and 1 × 10−6 m2/WK with lowest power of 100 W.
