The nan o-Al۲O۳ e ffect on glass transition temp erature of a new na nocomposite based on glycerol diglyci dyle ether: An EIS and DMTA study

Materials derived from epox y resin ha ve been widely used in polymer industry such as electrical insulati ng materials because of their rema rkable prop erties for i nstance mo derate mecha nical prop erties, great electrical properties and excell ent processability. Dy namic mecha nical thermal analysis (DMTA) is one of the ways to estim ate changes, which occur for polymeric materials in the b road range of tempera ture [۱]. S everal researchers have also studied the relaxation proce sses in pol ymeric syst ems using DMTA and Electrochemical Impedance Spectroscopy (EIS ) [۲] techniques and found that they are shifted according to the frequency used in the given method.
