제목 Rheological Properties of Various Fillers in Polylactic acid/Low-density Polyethylene Blends.
초록 Among the biodegradable polymers, PLA is considered as a promissing material to solve the environmental pollution caused by plastic wastes. However PLA have some weak mechanical property, brittleness and poor processability. For this reason, some researchers have tried polymer blend with materials that can compensate for weaknesses of PLA. In this study, We used Low density Polyethylene (LDPE) for dispersed phase for resolving disadvantage of PLA. To improve compatibility between PLA and LDPE, we added three inorganic fillers, hydrophilic fumed silica, hydrophobic fumed silica and hydrophobic organoclay as compatibilizer. In order to evaluate compatibilizer effect of various fillers, linear viscoelastic properties from small amplitude oscillatory shear (SAOS) test and nonlinear viscoelastic properties from elongational test are measured.
