Effect of Radical Initiators on the Rheological Properties and Toughness of Poly(Lactic Acid)/Poly(3‐Hydroxybutyrate‐Co‐4‐Hydroxybutyrate) Blends

open access: yesPolymer Engineering &Science, EarlyView.
Effect of mixing protocol on the size distribution of PHA domains in the PLA matrix. ABSTRACT In this study, poly(lactic acid) (PLA) and poly(3‐hydroxybutyrate‐co‐4‐hydroxybutyrate) [P(3HB‐4HB), a type of polyhydroxyalkanoate (PHA)], were melt‐blended at an 80/20 (wt/wt) ratio, and radical initiators were employed as reactive compatibilizers to enhance

Poly‐Ether‐Ether‐Ketone Melt Behavior in Fused Deposit Modeling Printing Moves

open access: yesPolymer Engineering &Science, EarlyView.
A thin solidified layer forms at the print bed during FDM of PEEK, reducing the effective shear height and raising the effective shear rate above the nominal value. Surface defects emerge once the effective shear rate exceeds a critical value of approximately 750 s−1.

Rheological Characterization of a Low‐Concentration Water‐Based Collagen Dispersion Under Extensional, Shear, and Oscillatory Deformation

open access: yesPolymer Engineering &Science, EarlyView.
Combined capillary and oscillatory rheology provided complementary insights into the linear, nonlinear, and extensional flow behavior of a 3 wt% collagen dispersion, improving the understanding of its processing‐relevant rheological characteristics. ABSTRACT This study presents an investigation of the extensional, shear, and oscillatory rheological ...
