Morphology And Mechanical Properties

The effects of four types of organoclay on morphology and mechanical properties of poly(lactic acid) (PLA)/propylene-ethylene copolymer (PEC) blends were investigated. The ratio of PLA and PEC was 80/20 by weight and the organoclay content was 5 phr. The morphology analysis showed that the addition of all oganocaly types could improve the miscibility of PLA and PEC blends due to the decreased of the domain sizes of PEC dispersed phase in the polymer matrix. The tensile properties showed Young’s modulus of the PLA/PEC blends was improved after adding clay treated surface with 25-30 wt% trimethyl stearyl ammonium.

Morphology And Mechanical Properties

In this article, the phase morphology and mechanical properties of poly (trimethylene terephthalate)/maleinized poly (octene-ethylene) copolymer blends are studied by using scanning electron microscopy (SEM), polarized optical microscopy (POM), universal material tester and charpy impact tester. The results suggest that the crystal size of the blends decreases obviously and POE component is partly served as nucleating agent for the crystallization of PTT. PTT and POE have good compatibility in blends because the dispersed phase of POE has even dispersion in blends when POE content is lower than 5%; however, the dispersion state of POE becomes poor when POE content is larger than 5%. The impact strength increases to maximum when the POE content is about 4 %. The tensile strength gets to maximum when POE content is 1-2 %.
