Combined Effect of Poly(hydroxybutyrate) and Plasticizers on
It was observed that both plasticizers improved the thermal stability of the PLA–PHB blend for times lower than 9 min. All samples showed a weight loss lower than 1 % after 6 min, which is the...
Combined Effect of Poly(hydroxybutyrate) and Plasticizers on
Poly (lactic acid) PLA, and poly (hydroxybutyrate) PHB, blends were processed as films and characterized for their use in food packaging. PLA was blended with PHB to enhance the crystallinity. Therefore, PHB addition strongly increased oxygen barrier while decreased the wettability.

Plasticization of Poly(3-hydroxybutyrate- co-3
In the last few decades, many efforts have been made to make poly (3-hydroxybutyrate) (PHB) and its copolymers more suitable for industrial production and large-scale use. Plasticization, especially using biodegradable oligomeric plasticizers, has been one of the strategies for this purpose.
- Are poly (lactic acid) & poly (hydroxybutyrate) bio-based polyesters suitable for short-life applications?
- In this sense, poly (lactic acid) (PLA) and poly (hydroxybutyrate) (PHB) are thermoplastic bio-based polyesters with highly promising perspectives for short-life applications [ 5 – 8 ].
- What is poly (3-hydroxybutyrate)?
- Poly (3-hydroxybutyrate) (PHB), which is biosynthesized by a wide variety of bacteria, is a biodegradable thermoplastic with biocompatibility and ecological safety. Therefore, it has great potential in applications such as surgical sutures, long-term carriers for drugs, and degradable plastics.
- What is poly hydroxybutyrate (PHB)?
- Poly-hydroxybutyrate (PHB) is one the most widely studied PHAs , . The physical properties of PHB are often compared to those of isotactic polypropylene because they have similar melting points, degrees of crystallinity and glass transition temperatures , .
- Do biodegradable plasticizers affect thermal and mechanical properties of poly(PHBV)?
- The effects of biodegradable plasticizers on the thermal and mechanical properties of poly (3-hydroxybutyrate- -3-hydroxyvalerate) (PHBV) were studied using thermal and mechanical analyses. Soybean oil (SO), epoxidized soybean oil (ESO), dibutyl phthalate (DBP) and triethyl citrate (TEC) were used as plasticizing additives.
- Does PHB increase oxygen barrier and decrease wettability?
- Therefore, PHB addition strongly increased oxygen barrier while decreased the wettability. Two different environmentally-friendly plasticizers, poly (ethylene glycol) (PEG) and acetyl (tributyl citrate) (ATBC), were added to these blends to increase their processing performance, while improving their ductile properties.
- Does PHB increase oxygen barrier in food packaging?
- Poly (lactic acid) PLA, and poly (hydroxybutyrate) PHB, blends were processed as films and characterized for their use in food packaging. PLA was blended with PHB to enhance the crystallinity. Therefore, PHB addition strongly increased oxygen barrier while decreased the wettability.
