Biodegradable Poly(butylene succinate) Composites Reinforced by Cotton Fiber with Silane Coupling Agent

Abstract

In this study, the use of cotton fiber (CF) as a filler in poly(butylene succinate) (PBS) and the effect of silane treatment on the mechanical properties, thermal stability, and biodegradability of PBS/CF composites are investigated. The results showed that the tensile strength of PBS was improved (15%–78%) with the incorporation of CF (10–40 wt%) and was further increased (25%–118%) when CF was treated with a silane coupling agent. Scanning electron microscopy (SEM) observation of the fracture surfaces of PBS/CF composites showed that there was slight improvement in fiber-matrix compatibility. Thermogravimetric (TG) analysis showed that the thermal stability of the composites was lower than that of neat PBS and decreased with increasing filler loading. The biobased carbon content of the composites increased with increasing CF content. The incorporation of CF (with and without silane treatment) in PBS significantly increased the biodegradation rate of the composites

Thermal behaviors and characteristics of polylactide/poly(butylene succinate) blend films via reactive compatibilization and plasticization

“…Glass transition temperature ( T g ), crystallization temperature ( T c ), cold crystallization ( T cc ), melting temperature ( T m ), and specific fusion enthalpy ( ∆H f ) were evaluated from the endothermic and exothermic peaks. The degree of crystallinity ( χ c ) of the blend film was calculated from the following Equation 2: where ΔH f, blend is the specific fusion enthalpy of the blend films, ΔH 0 f, PLA is specific fusion enthalpy of 100% crystalline PLA (93.6 J/g), and ΔH 0 f, PBS is the specific fusion enthalpy of 100 crystalline PBS (110.3 J/g) …”

Structure and properties of a compatible wood‐plastic composite prepared by using poly(butylene succinate)‐based polyurethane prepolymer

“…Marco Valente introduced recycled paper in high density polyethylene matrix composites which additivated with maleated PE. Also, silane coupling agents, such as 3‐aminopropyltriethoxysilane, 3‐aminopropyltrimethoxysilane, and N1‐3‐trimethoxysilylpropyldiethylene triamine have used as compatibilizers by Calabia . Although these studies showed that the mechanical properties and some other properties of materials were improved to a certain extent, they generally had some defects during the modification process, such as low reaction rate of the compatibilizers, low proportion of plant fiber, not to mention the establishment of the effective interface structure.…”

[23] Although these studies showed that the mechanical properties and some other properties of materials were improved to a certain extent, they generally had some defects during the modification process, such as low reaction rate of the compatibilizers, low proportion of plant fiber, not to mention the establishment of the effective interface structure. Furthermore, the extensive use of organic solvents such as dimethyl sulfoxide, tetrahydrofuran and toluene inevitably produced severe environmental pollution during their processing.…”

Investigations on Drilling of Bidirectional Cotton Polyester Composite

“…Development and characterization of composites produced from cotton fibers reinforced with various matrices have been explored by a few researchers. Cotton-epoxy [6], cotton-polyethylene [7], cotton-butylene succinate [8], cotton-phenolic [9], textile cotton-polypropylene [10], cotton-geopolymer [11], cotton-bionolle 3020 [12], cotton-vinyl ester [13], jute/cottonphenolic [14], cotton-polyester [15] are some of the promising systems.…”
