Thermorheological complexity in Nylon12‐Cork composites: Role of interfacial compatibilizer
Abstract
<jats:title>Abstract</jats:title><jats:sec><jats:label/><jats:p>Herein, we demonstrate how compatibilizers affect the thermorheological properties and morphology of engineering thermoplastic composites based on nylon and cork. Nylon12 was melt‐mixed with cork treated with four distinct compatibilizers with radically different chemical structures and compositions, respectively: (i) Octadecanamide (ODA), (ii) polyethylene‐graft‐maleic anhydride (PE‐g‐MA), (iii) polypropylene‐graft‐maleic anhydride (PP‐g‐MA), and (iv) (3‐aminopropyl)triethoxysilane (APTS). The rheological behavior was assessed using an oscillatory rheometer and the morphology was visualized using a scanning electron microscope. The rheological data were thoroughly analyzed using different formalisms based on empirical, phenomenological, and molecular origin, including the Carreau‐model, time–temperature superposition (TTS), Han plot, and van Gurp–Palmen (vGP) plot. It is observed that rheological data of neat nylon can be treated as themorheologically simple. However, the inclusion of cork makes the composite thermorheologically complex and increases the relaxation time (τ) by >50‐fold when compared to the neat polymer. As compatibilizers, ODA and PP‐g‐MA significantly lower τ, improve internal flow behavior, and demonstrate good cork distribution and dispersion. However, PE‐g‐MA does not affect the τ of composites significantly. The application of APTS as a compatibilizer enhances the interfacial interaction between Nylon12 and cork most significantly, which leads to a notable rise in τ, and the composite's elastic modulus surges by two orders in magnitude compared to neat Nylon. Additionally, the polymer melt flow becomes elastically dominant. Finally, it is observed that the Han plot offers a better insight into the correlation between changes in the thermorheological behavior and the microstructural modifications to the composites.</jats:p></jats:sec><jats:sec><jats:title>Highlights</jats:title><jats:p><jats:list list-type="bullet"> <jats:list-item><jats:p>Utilizing cork particles as a sustainable raw material for engineering thermoplastics.</jats:p></jats:list-item> <jats:list-item><jats:p>Quantifying compatibilizer's impact on rheological properties of polymer composite.</jats:p></jats:list-item> <jats:list-item><jats:p>Illustrating how interfacial interaction affects thermorheological complexity in composites.</jats:p></jats:list-item> <jats:list-item><jats:p>Visualizing morphological change in nylon‐cork composite with interfacial interaction.</jats:p></jats:list-item> <jats:list-item><jats:p>Producing lightweight engineering polymer composites using cork as a filler.</jats:p></jats:list-item> </jats:list></jats:p></jats:sec>
