Abstract Previous studies on epoxy foams were subjected to the specific property, and improvements in thermal insulation or dielectric property usually accompanied by sacrifice of mechanical strength stability. The current research reported a high‐performance foam pre‐curing process using E‐51/DDS expandable microsphere (EMP) as polymer matrix physical blowing agent, respectively. effect EMP loading structure & was reported. mean diameter E‐51/EMP range 19–21 μm. compression fit for power‐law model its integrity well maintained during compressive test. Compared with bulky epoxy, significant decrease conductivity 62.93% observed 10 wt% EMP‐filled foam. showed superior stabilities, T 5% over 300°C. constant decreased 54.5% from 4.92 2.24 (10 EMP). Notably, there percolation phenomenon (6 wt%) regarding This study provides lightweight, robust, high‐temperature‐resistant, low‐dielectric‐constant wide application prospects buoyant, electronic packaging, energy‐saving industries.

This experimental investigation focused on coating of functionalized graphene oxide (FGO) the mild steel to minimize corrosion, using a new method. Prior coating, fundamental chemical and morphological structures FGO were studied with aid some characterization techniques: X-ray diffraction (XRD), Raman, scanning electron microscopy (SEM) transmission (TEM). Various epoxy/FGO formulations 10, 20, 30, 40 50 ppm prepared coated substrate, adopting dip Immersion test was carried out observe corrosion inhibition efficiency graphene. The adsorption isothermal behavior also various models compared data obtained from results. From results obtained, formation irregular rough patches separation platelets like zebra lines indicated nanoparticles, as observed through analysis. occurrence sharp peak at 24.3° in XRD pattern depicted existence nanoscale. Electrochemical impedance (EI) potentiodynamic polarization (PP) studies reported maximum 87% concentration epoxy/FGO. It evident that an increasing exhibited significant resistance both studies. bonding energy randomly oriented reduced removal metal, delaying crack propagation tortuous path surface. These established significance applicability this study relevant industries.
