“…However, at the 8% A669 level, the flexural strength and modulus decreased by 11.05%. As predicted, elastomer A669 showed a significant improvement on impact strength, but it reduced rigidity and strength, like other flexible polymers .…”

It is important for wood plastic composites to possess satisfactory toughness and stiffness in practical applications, such as construction formworks. In this study, an elastomer‐grafted polyolefin (A669) was introduced to improve the toughness of wood flour/polypropylene (WF/PP) composites, with talcum powder used as the reinforced phase to maintain the flexural strength and stiffness of the WF/PP composites. The impact strength and bending properties of the composites were tested. Differential scanning calorimetry, dynamic mechanical analysis, and scanning electron microscopy were used to analyze this composite system. Test results show that the combination of A669 and talcum powder can provide the WF/PP composites with both good toughness and flexural properties. The optimum additions of A669 and talcum powder were 6% and 9%, respectively. Talcum powder plays an important role in the heterogeneous nucleation, which is helpful for increasing crystallinity and improving flexural properties. However, this function could be offset by the addition of A669. The WF/PP composites with elastomer A669 and talcum powder present more viscosity characteristics and rougher fracture surfaces. In addition, the WF/PP composites containing elastomer A669 and talcum powder have better processability. POLYM. COMPOS., 40:1335–1341, 2019. © 2018 Society of Plastics Engineers

“…[17,27] Dynamic response of the PTT/PBAT blend indicates that the storage modulus is decreasing with increasing PBAT content, which is because of the enhancement of elastic properties. The same dynamic behavior is also observed in reported blends, such as PLA/PBAT [27,32] and PTT/metallocene linear low density polyethylene (m-LLDPE) [33] blends. Both PLA/PBAT and PTT/m-LLDPE blends storage modulus was decreased with the addition of PBAT and m-LLDPE matrix, respectively, which is because of the presence of long alkyl chain of PBAT and m-LLDPE matrix, and it leads to enhanced flexible nature.…”

Novel blends were prepared from biobased poly(trimethylene terephthalate) (PTT) and poly(butylene adipate-coterephthalate) (PBAT) using a twin screw extrusion process as a function of different weight ratios. Thermal stability, mechanical, and interfacial properties of PTT/PBAT blends were investigated using a thermogravimetric analyzer and mechanical analyzer. Phase behavior and surface morphology of the blends were characterized using scanning electron microscopy. Interfacial bonding value of the PTT/PBAT blend was evaluated from the Pukanszky empirical relationship. Viscoelastic properties of PTT/PBAT blends were investigated using the dynamic mechanical analyzer. PTT/PBAT blend exhibited higher thermal stability than the neat PTT matrix. The entire blend showed better interfacial adhesion between the matrixes. Storage and loss modulus of the PTT/PBAT blend reduces with increasing PBAT content. PTT/PBAT blend exhibited higher impact energy than the neat PTT matrix, because of its flexible and amorphous nature of PBAT polymer and increasing toughness.

“…PTT is endowed with good physical and chemical properties like dimensional stability, heat resistance, good chemical stability, resistant to stretching, low moisture absorption or quick drying, easy processability, and recyclability which make all PTT‐based composites very useful in diverse industrial applications . However, their low impact strength, low heat distortion temperature, and low viscosity for processing limit their applications in many ways. Polymer blending is one of the major techniques which can overcome these limitations.…”

Theoretical analysis is carried out to predict the nature of selective localization of multi‐walled carbon nanotubes (MWCNTs) in poly(trimethylene terephthalate/polyethylene (PTT/PE) blends. In agreement with theoretical data experimental results clearly indicate that MWCNT prefers to get associated with PTT phase than with PE. Molecular interactions responsible for such selective localization of MWCNT to PTT component can be attributed to mutual and collective π–π interactions possible between the aromatic moieties present in PTT and MWCNT. In addition, the reinforcing effect of MWCNT in the PTT/PE system was determined using tensile analysis and the morphological features of blends and blend nanocomposites are studied using scanning electron microscope (SEM). Compared to the PTT/PE blend system MWCNT incorporated blend nanocomposites show better mechanical properties. The elongation at break of the blend system is seen to rise with increasing amount of PE content. Among various blend nanocomposites, we have investigated the nanocomposites with higher PTT content show higher tensile strength and Young's modulus. The blend nanocomposite with 90/10/1 composition shows 12% increment in Young's modulus and as much as 80% increment in tensile strength compared to 90/10 blend system which signifies the role MWCNT plays in the blend system.
