At same filler content, polymer nanocomposites show different properties depending on dispersion quality. The well-known method to enhance the degree of dispersion is to introduce the compatibilizer which have affinity to both components. Maleic anhydride grated polymers in terms of compatibilizer are usually used at nonpolar/clay nanocomposites, e.g. PP, LDPE, PS etc. Likewise, researches to reinforce the dispersion quality have been investigated actively whereas few those to assess the dispersion states have been researched relatively so far. In this study rheology measurement was introduced as a tool of assessing dispersion quality because of sensitivity to internal structure change. Especially, LAOS(Large Amplitude Oscillatory Shear) test analyzed by FT(Fourier Transform)-rheology was focused on acquiring the degree of dispersion. |
