“…A minimum of five test bodies were tested. 13 C MAS NMR spectra were recorded on a AVANCE-II spectrometer (Bruker Corporation, Billerica, MA, USA) in a 14.1 T magnetic field ( 13 C resonance frequency 150.9 MHz) using a home-built MAS NMR probe for 25 × 4 mm Si 3 N 4 rotors. In all experiments, the sample spinning frequency was set to 12.5 kHz.…”

“…Wood flour and sawdust (SD) are already used to produce wood polymer composites, typically together with traditional polymers such as polypropylene and polyethylene [9,10]. Wood flour has also been evaluated as a filler for biopolymers such as PLA [11], PHB [12] and polybutylene succinate (PBS) [13]. Chitin is one of the most abundant polymers in nature.…”

Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) is a biobased and biodegradable polymer. This polymer is considered promising, but it is also rather expensive. The objective of this study was to compound PHBV with three different organic fillers considered waste: human hair waste (HHW), sawdust (SD) and chitin from shrimp shells. Thus, the cost of the biopolymer is reduced, and, at the same time, waste materials are valorised into something useful. The composites prepared were characterised by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), tensile strength and scanning electron micrograph (SEM). Tests showed that chitin and HHW did not have a reinforcing effect on tensile strength while the SD increased the tensile strength at break to a certain degree. The biodegradation of the different composites was evaluated by a soil burial test for five months. The gravimetric test showed that neat PHBV was moderately degraded (about 5% weight loss) while reinforcing the polymer with organic waste clearly improved the biodegradation. The strongest biodegradation was achieved when the biopolymer was compounded with HHW (35% weight loss). The strong biodegradation of HHW was further demonstrated by characterisation by Fourier-transform infrared spectroscopy (FTIR) and solid-state nuclear magnetic resonance (NMR). Characterisation by SEM showed that the surfaces of the biodegraded samples were eroded.

“…[20] At present, a variety of compatibilizers have been used by many researchers to improve the compatibility between WF and PBS. For instance, Xiao [21] used a kind of cellulose fatty acid ester as macromolecular coupling agent in PBS/WF composites. Marco Valente [22] introduced recycled paper in high density polyethylene matrix composites which additivated with maleated PE.…”

Wood‐plastic composites (WPCs) are sustainable green material with extensive application prospects in both industry and daily life. So a more convenient, environmentally friendly and effective method is crucial. In this work, WPC was composed by 60 wt% poly(butylene succinate) (PBS) matrix, 10 wt% compatibilizer, and 30 wt% wood flour (WF) through extruder and injection machine. The effects of PBS diol‐based polyurethane prepolymer (PBSPUP) compatibilizer on the structure and properties of WPCs were investigated. Compared with the WF30P70 sample, the tensile strength and the elongation at break of WF30PU10P60 sample had an increase of 52.1% and 125.0%, respectively. And the equilibrium water absorption of WF30PU10P60 was reduced from 4.79% (WF30P70) to 3.57%, the flow properties of WF30PU10P60 were also improved at the same time. Apparently, the composites containing the poly(butylene succinate) diol‐based polyurethane prepolymer (PBSPUP) compatibilizer exhibited improved mechanical properties and thermal performance as shown by the results of scanning electron microscopy, differential scanning calorimetry, X‐ray diffraction, water absorption, rheological property analyses, and so on. Toward this end, the special PBSPUP interface structure played an important role in improving the properties of the WPC.

“…However, its extensive application is limited due to the high cost compared to petroleum-based polymers. Another approach to forming biodegradable plastics is to blend low-cost macromolecules, such as protein [10,11] , starch [12,13] and natural fiber [14,15] with high performance biodegradable plastics. Several studies on the development of bio-based plastics derived from soy protein, wheat protein, corn zein, and sunflower protein have been conducted [10].…”

Biodegradable composites from poly (butylene succinate-co-butylene adipate) (PBSA) and Taihu Lake (Wuxi, China) blue algae were prepared by melt blending. The property and structure of biocomposites were investigated. By adding extra amount of water to blue algae, the formulated blue algae acted as a plastic in the composites during blending, and exhibited a reinforcing effect on the PBSA matrix. With increasing blue algae content, the thermal stability of the composites decreased; the tensile strength at break and elongation at break of the composites reduced, but the Young's modulus of the composites increased. However, the composite with 30% blue algae loading still exhibited good mechanical performance (tensile strength at break of 21.3 MPa, elongation at break of 180%). The fabrication of value-added PBSA/algae composites appeared as an effective approach to reduce the secondary environmental pollution of Taihu blue algae.
