Research on IR and Heat Transfer Characteristics of Molybdenum-Sputtered Polyamide Materials

Abstract

Demand for the development of the convergence industry, research studies on heat transfer, thermal characteristics, semiconductors, motors, and batteries using special materials have come to the fore. Meanwhile, molybdenum (Mo) exhibits relatively small inorganic qualities, and the thermal conductivity rate is applied to various fields. In this study, in-depth characteristics were considered regarding the concentration of thermal characteristics and IR characteristics. In particular, this study conducted a thicker molybdenum layer sputtering work than previous studies and examined it in detail at high temperatures by pore size. This study calculated each phase temperature of the molybdenum-sputtered specimens in the steady state according to the heat transfer theory. When the molybdenum-sputtered fabric’s metal layer pointed to the outside air, the heat transfer rate (Q) was high at 5748.3 W. In contrast, if the molybdenum-sputtered film’s metal layer pointed toward the heat source, the heat transfer rate (Q) was low at 187.1 W. As a result of measuring the IR transmittance, the infrared transmittance of the molybdenum-sputtering-treated sample was significantly reduced compared to the untreated sample. It is believed that the molybdenum-sputtering polyamide samples produced in this study can be applied to multifunctional military wear, biosignal detection sensors, semiconductor products, batteries, etc., by utilizing excellent electrical properties, stealth functions, and IR-blocking properties.
