“…It can be seen that PBAT/PLA and PBAT/sc‐PLA 12,37 blends show poor mechanical properties due to the weak compatibility between PBAT and PLA. When the compatibility strategy is used, the mechanical properties of PBAT/PLA blend improve obviously 10,28,38 . However, compared with these compatibilized PBAT/PLA blends, the PBAT/PLA/MG shows higher mechanical performance.…”

Poly(butylene adipate–butylene terephthalate) (PBAT) and poly(lactic acid) (PLA) biodegradable composites have been prepared by the melt‐blending method using a new methyl methacrylate and glycidyl methacrylate random copolymer (MG) as compatibilizer. The compatibilization reaction between the epoxy functional groups in MG and the carboxyl groups in PBAT and PLA resulted in the formation of branched PBAT‐co‐MG‐co‐PLA macromolecules and improved compatibility. The compatibilization effect induced higher glass transition temperature for PBAT and PLA. The addition of MG had little influence on the melting process of PBAT. However, the fine miscibility between PLA and MG inhibited cold crystallization and the following melting behavior of PLA. The compatibilization effect promoted the uniform dispersion and smaller particle size of the PLA phase, which enhanced the heterogeneous nucleation effect of PLA and induced higher crystallization temperature of PBAT. Dynamic rheological tests showed that PBAT/PLA/MG blends exhibited higher complex viscosity and modulus than PBAT and PBAT/PLA blend, proving the improved interfacial interaction and melt strength. Compared with the PBAT/PLA composite, PBAT/PLA/MG blends showed much better ductility and stiffness balance because of the compatibilization effect of MG. When MG concentration was 6 wt%, the blend achieved a maximum strain of 694% and tensile strength of 49.3 MPa, which were 1.8 and 4.3 times higher than those of the PBAT/PLA composite. © 2022 Society of Industrial Chemistry.

“…At present, the modification method of PBAT is mainly blending modification, such as polylactic acid (PLA) [ 2 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ], polybutylene succinate (PBS) [ 20 ], polyglycolic acid (PGA) [ 21 , 22 , 23 , 24 , 25 , 26 , 27 ], polycaprolactone (PCL) [ 28 , 29 ], poly(propylene carbonate) (PPC) [ 30 , 31 , 32 , 33 ], poly(ethylene-co-vinyl alcohol) (EVOH) [ 34 ], starch [ 35 , 36 ], calcium carbonate [ 37 , 38 ], and other materials [ 39 ]. PBAT was also modified by chain extension modification [ 40 ].…”

The main problem of manufacturing with traditional biodegradable plastics is that it is more expensive than manufacturing with polymers derived from petroleum, and the application scope is currently limited due to poor comprehensive performance. In this study, a novel biodegradable poly(butylene adipic acid/terephthalate-co-glycolic acid) (PBATGA) copolyester with 25–60% glycolic acid units was successfully synthesized by esterification and polycondensation using cheap coal chemical byproduct methyl glycolate instead of expensive glycolic acid. The structure of the copolyester was characterized by ATR-FTIR, 1H NMR, DSC, and XRD; and its barrier property, water contact angle, heat resistance, and mechanical properties were tested. According to the experiment result, the PBATGA copolyesters showed improved oxygen (O2) and water vapor barrier character, and better hydrophilicity when compared with PBAT. The crystallization peaks of PBATGAs were elevated from 64 °C to 77 °C when the content of the GA unit was 25 mol %, meanwhile, the elongation at the break of PBATGA25 was more than 1300%. These results indicate that PBATGA copolyesters have good potentiality in high O2 and water vapor barrier and degradable packaging material.

“…In the search for better properties, Zhou et al incorporated two phosphorous-containing ionic liquids in melting blends of PBAT and poly(lactic acid) (PLA). Due to the interaction among ionic liquids and polymers, the toughness, flame retardancy, and processability showed improvement [14]. Yap et al developed a composite based on a blend of PBAT and PBS filled with rice rusk.…”

“…The diffraction angles at 18, 21, 23.5, 24.4 and 25 designated as representative of PBAT crystalline planes showed variable width and intensity.The more significant was centred at 25˚. Ordinarily, the current works reported PBAT 2θ reflections at 16.1˚, 17.3˚, 20.2˚, 23.1˚ and 25.0˚ correlated to the crystallographic planes (0 -11), (010), (−111), (100) and(1 -11), respectively[12] [13][14] [23][35]. We credited this variation solely or jointly to the factors such as different manufacturers and grades, little technical information on copolymer composition, melt flow rate, density, and processing conditions (temperature window, residence time, screw rotation and others).…”
