Silver nitrate (AgNO3), chloroplatinic acid (H2PtCl6·6H2O), poly(vinylpyrrolidone) (PVP), anhydrous ethylene glycol (EG), and sodium chloride (NaCl) were purchased from Sigma Aldrich Chemical (Yongin, Kyeonggi-do, Korea) for the syntheses of AgNWs. A cycloaliphatic-type epoxy resin was purchased from Daicel Chemical Industry (Minato-ku, Tokyo, Japan). The anhydride-type curing agent, hexahydro-4-methylphthalic anhydride, and silver acetate (AgAc) were purchased from Sigma Aldrich Chemical. An imidazole-type catalyst, 1-(2-cyanoethyl)-2-ethyl-4-methylimidazole (imidazole), was purchased from TCI Chemical (Chuo-ku, Tokyo, Japan). The synthesized AgNW was purified using the washing method. Isopropyl alcohol (IPA), purchased from SK Chemical (Seongnam-si, Kyeonggi-do, Korea), was chosen as the solvent because of its low boiling point and capacity as a good stabilizer for AgNWs.

Bisphenol A type epoxy resin, YD-128, was obtained from Kukdo Chemical (Seoul, Korea). Hexahydro-4-methylphthalic anhydride (HMPA), as the hardener for epoxy resin, and 2-ethyl-4-methylimidazole (EMI), as the catalyst, were purchased from Sigma-Aldrich (Yong-In, Korea). Furthermore, 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane (KBM-303), a coupling agent, was provided by Shln-Etsu Chemical Co., Ltd. (Tokyo, Japan). Aluminum oxides of spherical shapes with a median diameter of 14.4 μm (Al2O3, DAB-10SI) were purchased from Denki Kagaku Kogyo Kabushiki Kasisha (Tokyo, Japan). Boron nitride filler in the shape of a single-crystal platelet, with a mean particle size of ~45 μm and a surface area of 0.6 m2·g−1, was purchased from Momentive Performance Materials, Inc. (Waterford, NY, USA). All materials were directly used without purification or modification.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
