AbstractPolyimides, high-performance polymers with superior properties such as high temperature stability, resistance to solvents and high strength, can be used in high-tech applications of the aerospace and aviation, medical or electronics industry in different forms (film, fiber, nanofiber, membrane, foam, adhesive or coating). Among these applications, coating has a special place and is used to develop advanced structures having high temperature resistance, flame retardancy and etc. for high tech industries via an economical and feasible way. Therefore, in this review, we aimed to report the broad application status of polyimide coatings by reviewing publications, patents and commercial products. Thus, this study can assist in selecting suitable polyimide types and production methods for polyimide coating applications and in understanding their applicability for future products.

Because of the superior material properties of diamond, high performance in high-temperature power device application is demonstrated in both the computational and the experimental studies. A calculated Baliga limit of diamond Schottky barrier diode (SBD) based on 1D model indicates that an increase in on-resistance is highly expected within the high blocking voltage region and will be remarkable at high temperature conditions. Because of the high barrier height of diamond SBDs, the reverse leakage current is suppressed even at high temperatures. From the high-temperature stability test, stable interfaces of metal/diamond contact with constant Schottky barrier height have been confirmed. The SBD works for more than 1500 hrs at 400oC.

Abstract To increase the content of boron in soluble polyborosilazanes (PBSZs) (the Si/B ratio should be less than 3), we introduce a successful one-pot synthesis method of a precursor by reaction with tris(dichloromethylsilylethyl)borane (TDSB), boron trichloride (BTC) and hexamethyldisilazane (HDMS) that satisfies the above conditions. The precursor was successfully transformed to SiBCN fibers by electrospinning technology. The resulting SiBCN ceramic material produced by the new route has high performance and high-temperature resistance against crystallization. Furthermore, we have analyzed the mechanism of the synthesis and ceramization of the new soluble precursor by NMR, FT- IR and TG- MS, and the high- temperature stability of the resulting SiBCN powder has been analyzed a by DTA, XRD and SEM.

Abstract Recently, high-temperature stability is a challenge in a number of microwave absorption materials. Hence, researchers are still searching for a novel material system preferably with a high-temperature resistance to be applied in the field of microwave absorption. Here, in the current study, toward this aim, lanthanum (La) doped strontium titanate (SrTiO 3 ) blended with TiO 2 were fabricated by hot-press sintering in vacuum. The as-prepared samples are denoted as TiO 2 -Sr 1- x La x TiO 3 with x varying from 0.1 to 0.3 in steps of 0.1. Scanning electron microscope (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscope (XPS), and microwave vector network analyzer were carried on to study their morphology, phase composition, structure, electromagnetic and microwave absorption properties, respectively. It is revealed that the La atom was efficiently doped at the Sr-site in SrTiO 3 . Benefiting from the tunability of its dielectric and impedance properties, TiO 2 -Sr 1- x La x TiO 3 can be utilized in a highly efficient way to absorb microwave radiations with a decent design. Results illustrated that TiO 2 -Sr 1- x La x TiO 3 ( x =0.2) with a thickness of only 0.42 mm exhibits a high microwave absorption efficiency of -40.89 dB and can achieve a 2.82 GHz bandwidth of reflection loss value below -5 dB. Thus, TiO 2 -Sr 1- x La x TiO 3 composites ceramics can be served as an opening opportunity for the application of high-temperature stability and tunable high-performance effectiveness microwave absorption materials in stealth technology and information security.
