“…A similar type of observation has been reported in the partially cross-linked PBS in the presence of DCP initiator. 37 However, there was no change observed in the impact strength of PBS after incorporation of 5 wt % MAH-g-PBS compatibilizer. Unlike impact strength of compression molded PBS/30 wt % kenaf composites 38 and injection molded PLA/30 wt % wheat straw composites, 39 there is a trend for impact strength of injection molded PBS composite to increase with miscanthus fibers loading up to 40 wt %.…”

Biocomposites from poly(butylene succinate) (PBS) and perennial grass (miscanthus fibers) were successfully prepared by extrusion and injection molding methods with different fiber loadings. The tensile strength of uncompatibilized PBS/miscanthus composites was much lower compared to that of neat PBS. Unlike tensile strength, the flexural and impact strengths were significantly enhanced after incorporation of miscanthus fibers into the PBS matrix. The enhanced flexural strength was attributed to the reinforcing effect of miscathus fibers. The fiber pull-out mechanism is likely responsible for the observed impact strength improvement. Addition of 5 wt % maleic anhydride (MAH) grafted PBS (MAH-g-PBS) into PBS composites showed a significant improvement in tensile and flexural strength compared to the corresponding uncompatibilized composites and neat matrix. For example, the PBS composites with 50 wt % miscanthus fiber and 5 wt % MAH-g-PBS resulted in 22, 139, and 47% improvements in tensile, flexural, and impact strength compared to neat PBS. These improvements were attributed to the enhanced interfacial interaction between the components, as confirmed by adhesion parameter values and by surface morphological analysis. The load-bearing capacity of the compatibilized and uncompatibilized PBS/miscanthus composites was analyzed using a mathematical model. Overall, this study provides an option for preparing a sustainable biocomposite with superior mechanical and thermo-mechanical properties.

“…Two notable crystallization peaks in the range of 30–90°C were detected corresponding to the PHBV and PBS components, respectively. The sharper crystallization peaks at higher temperatures (i.e., c 2 , d 2 , and e 2 , Figure ) are more related to the PBS phase because the crystallization rate of PBS could be significantly enhanced by partial crosslinking . A direct evidence is given by the POM observation (to be discussed below) that PBS showed faster crystallization prior to the PHBV.…”

“…A direct evidence is given by the POM observation (to be discussed below) that PBS showed faster crystallization prior to the PHBV. Although the content of PBS in the blends is only 20 wt %, it was the PBS component that dominantly crosslinked leading to the faster crystallization . Consequently, the peaks b 0 and c 0 (Figure ) become weak and even disappear with increasing the DCP content.…”

“…The melting temperatures of PHBV and PBS in the blends decrease with DCP content (Figure ) due to the imperfection of crystals which relate to branched/crosslinked polymer chains . The glass transition process of PHBV became less pronounced without changing the glass transition temperature ( T g ‐PHBV , Figure ).…”

Partially crosslinked poly(β‐hydroxybutyrate‐co‐β‐hydroxyvalerate)/poly(butylene succinate) (PHBV/PBS) and poly(β‐hydroxybutyrate)/poly(butylene succinate) (PHB/PBS) blends were prepared by melt compounding with dicumyl peroxide. The effect of partial crosslinking on crystallization of the PHBV/PBS and PHB/PBS blends was investigated systematically. Differential scanning calorimetry results showed that the overall crystallization rates of both PHBV and PBS in their blends were enhanced considerably by the partial crosslinking. Similar results were also detected in the PHB/PBS blends. The polarized optical microscope observation displayed that the nuclei density of PHBV was increased while the spherulitic morphology did not change much. Conversely, the PBS spherulites turned into cloud‐like morphology after the partial crosslinking which is a result of the decrease in spherulite size, the reduction in interspherulite distance and the interconnection of fine PBS domains. Wide angle X‐ray diffraction patterns confirmed the enhancement in crystallization of the PHBV/PBS blends after the partial crosslinking without modification on crystalline forms of the PHBV and PBS components. © 2014 Wiley Periodicals, Inc.

A "green" vinyl ester resin (GVER) is investigated for use in structural applications. The GVER was formulated using a monodisperse vinyl ester created via a novel synthetic route capable of using bio-waste material from paper and biodiesel industries. The GVER was used either as a neat resin or as blended with a commercial vinyl ester resin. The processing viscosity and gel times are investigated. The GVER reaches a similar viscosity as the commercial resin with only half the styrene monomer content, thereby reducing the volatile organic compounds associated with manufacturing. Composites of the GVER matrix reinforced by carbon fabric were tested for their tensile and flexural properties. The mechanical performance of the GVER compares favorably with commercial resin and provide a route for composites manufacturing from sustainably sourced vinyl ester matrix.
