“…[27,33,60] As it has been described previously the vegetable oil-derived plasticizers positively contribute to the overall thermal stabilization of P3HB formulations, which is an interesting feature if we consider the relatively narrow processing window of this polymer. The increase in the onset degradation temperature for different polymers after plasticization with vegetable oil derivatives has been previously reported by Garcia-Garcia et al [53] They reported an increase in the onset degradation temperature of neat P3HB of 25 and 30 °C after plasticization with 5 phr ELO and 5 phr ESBO respectively. Chieng et al [35] also obtained a remarkable increase in the onset degradation by 40 °C of neat PLA by the addition of 5 wt% epoxidized palm oil (EPO).…”

“…Similar tendency can be observed for the elastic modulus, which tends to stabilize to values around 1600 and 1450 MPa for plasticized P3HB formulations with MLO and EFAE respectively. Garcia-Garcia et al [53] also observed a decrease in tensile strength and tensile modulus of neat P3HB with increasing content of different plasticizers from epoxidized linseed oil (ELO) and epoxidized soybean oil (ESBO).…”

Poly(3‐hydroxybutyrate), P3HB is a thermoplastic polyester synthesized from bacterial fermentation with potential uses in packaging due to its biodegradability. Nevertheless, P3HB is a fragile material and its processing temperature window is very narrow which restricts its use. This study explores the potential of vegetable oil‐derived plasticizers, i.e., maleinized linseed oil (MLO) and an epoxidized fatty acid ester (EFAE) in the 5–20 phr range as environmentally friendly solutions for P3HB industrial formulations with improved toughness. The results show that optimum balance between ductile properties is achieved with low plasticizer content (5 phr) for both plasticizer types. Elongation at break and the impact resistance are increased by 28 and 71% respectively after addition of 5 phr MLO. With regard to EFAE, the elongation at break is improved by 40% and the impact resistance is increased to twice the value of P3HB. Another effect that both plasticizers provide is the thermal stabilization with a delay in the onset degradation temperature.

“…It is also worthy to note the additional stabilization that ECSO and MCSO provides with T 5% values over 330-331°C with 1 wt% ECSO or MCSO while higher ECSO or MCSO content leads to a small decrease in thermal stability, probably due to a plasticizer excess. This behavior has been reported previously with other vegetable oil-derived compatibilizers/plasticizers [49,50]. Similar trend can be seen for T 50% .…”

Abstract. This research work aims at the compatibilization of poly(lactic acid)/poly(butylene adipate-co-terephthalate), PLA/PBAT binary blends by using cottonseed oil derivatives, i.e. epoxidized (ECSO) and maleinized (MCSO) cottonseed oil. The potential of these vegetable oil-based compatibilizers are compared versus the effects of a conventional styreneacrylic oligomer. The base PLA/PBAT binary blend composition was 80 wt% PLA/20 wt% PBAT and the amount of compatibilizer was set to 1 and 7.5 wt%. The effects of the different compatibilizers were evaluated on PLA/PBAT films in terms of mechanical and thermal properties as well as blend's morphology by field emission scanning electron microscopy (FESEM). Complementary, biodisintegration tests in controlled compost soil and surface properties were evaluated to assess the effects of the compatibilizers. Addition of 1 wt% ECSO and MCSO led to a remarkable increase in the elongation at break up to values over 100% with regard to neat PLA. Despite this, maximum elongation at break was obtained for the compatibilized PLA/PBAT blend with 7.5 wt% MCSO, reaching values of about 321.2% respect neat PLA keeping mechanical resistant properties, such as Young's modulus and tensile strength, at high levels. Therefore, vegetable oil-derived compatibilizers stand out as environmentally friendly additives for PLA/PBAT binary blends with improved properties.

“…This phenomenon positively contributes to improving the elongation at break compared to uncompatibilized PLA‐DE composite. Regarding some previous studies, it has been observed that epoxidized or maleinized vegetable oils, such as palm oil, cottonseed oil, flaxseed oil, among others, produce a plasticizing effect in thermoplastic matrices at relatively low concentrations …”

Environmentally friendly composites from poly(lactic acid) (PLA) and diatomaceous earth (DE) were successfully manufactured by extrusion, followed by injection moulding. DE was used as a filler; several compatibilizer/coupling agents, namely (3‐glycidyloxypropyl)trimethoxysilane, epoxy styrene acrylic oligomer and maleinized linseed oil, were used to improve polymer–filler interactions. Mechanical characterization was carried out by standard tensile, impact and hardness tests while morphological characterization of the fractured surfaces was conducted by field emission scanning electron microscopy. The effect of DE was evaluated by differential scanning calorimetry and dynamic mechanical thermal behaviour. The results show that the addition of DE provides an improved tensile modulus and induces more brittle composites due to stress concentration phenomena. The addition of compatibilizers in PLA‐DE positively contributes to improve ductile properties, thus leading to high environmental efficiency materials with balanced mechanical properties. Specifically, the compatibility improvement between the PLA and DE was good with maleinized linseed oil and contributed to improving the impact strength, which is a key factor in PLA‐based composites due to the intrinsic brittleness of neat PLA. © 2019 Society of Chemical Industry
