“…Viscoelastic materials, as an important category of engineering application materials, had been widely studied. Many researches illustrated that viscoelastic coating had special protective performance which could be used in practical projects [1,2,3,4]. The researches of damping capacity on storage modulus , loss modulus and composite loss factor through microscopic and macroscopic analyses of mechanical properties, thermal stability and internal friction had proved the mechanism of damping capacity [5,6,7].…”
