Statistical optimization of compatibilized blends of poly(lactic acid) and acrylonitrile butadiene styrene

Abstract

A mixture design of experiment and subsequent regression analysis was used to study the effects of two additives on blends of poly(lactic acid) (PLA) and acrylonitrile butadiene styrene (ABS). Statistical analysis was used to find a blend with a balance of high toughness, strength, and stiffness. The blends were prepared by lab scale reactive extrusion and injection molding. Leastsquare regression models of statistically significant effects were built by analysis of variance (ANOVA). Using these models, optimization studies were used to study the predicted maximum values of each measurement criteria. Very large increases were seen in the measured responses with relatively small changes in additive content. Compared to the neat blend without additives, the impact strength was increased by over 600%, the elongation at break was increased by over 1000%, the tensile strength increased by 11%, and the tensile modulus increased by over 7%. Surprisingly, the composite optimization, which included all measured criteria, occurred at a point that allowed all four criteria values to remain very close to their individual maximums. The result is a partially biobased blend that does not sacrifice strength or stiffness to achieve very high toughness.

“…Further, the contact angle values of DUDCBz‐EP matrix and f ‐PFC/DUDCBz‐EP composites were statistically analyzed by applying t ‐test in accordance with the previous reports . T ‐Test was calculated by computation method and results of the t ‐test were compared between the DUDCBz‐EP matrix and various weight percentages of (1, 3, and 5 wt%) f ‐PFC/DUDCBz‐EP composites (Table ).…”

Using constrained mixture design method for optimizing the properties of organoclay filled ethylene-octene copolymer nanocomposites

“…The significance of each term can be determined based on its probability value (P-value). Significant term should have the probability value more than 95% (P-value0.05) and the probability of insignificant term will have the value less than 95% (P-value0.05) [34,35]. Therefore, the insignificant terms were omitted here from the final analysis and results.…”

“…ABS is composed of acrylonitrile, butadiene, and styrene; it has strength and rigidity. The toughness in ABS is given by the rubbery part of polybutadiene in the block copolymer (Vadori et al, 2017). ABS has been widely used for electrical and electronics goods, automotive parts, and household appliances.…”
