Effects of E44 and KH560 modifiers on properties of distillers grains poly(butylene succinate) composites

Abstract

In this account, the interaction between E44 and KH560 modifiers and poly(butylene succinate)‐distillers grains (PBS/DGs) composite system was studied experimentally and theoretically by means of molecular dynamics simulation. The PBS/DG biodegradable composites were prepared by melt blending the modified DG and PBS, and composting degradation tests were carried out for a period of 75 days. The effect of E44 and KH560 modifiers on the interfacial features, tensile characteristics, thermal stability and degradation properties of PBS/DG composites were examined. The results showed that both χ and Emix significantly decreased in the composite system, indicating that PBS and DG became easier to mix together in presence of E44 and KH560. Also, the interface effect of DG and PBS improved after the modification with KH560. The mechanical properties of the composites remarkably enhanced when DG was treated with 2% KH560. When compared with PBS, the tensile strength and elongation at break were boosted by 23.66 and 33.18%, respectively. After composting degradation for 75 days, the mass loss rate of PBS/DG reached 42.82%, corresponding to 5.90 times higher than that of pure PBS. Overall, the comprehensive properties of the composites improved. POLYM. COMPOS., 40:1499–1509, 2019. © 2018 Society of Plastics Engineers

Secondary silane grafting on aramid fibers improves the interfacial bonding performance in textile composite materials

“…Under the action of curing reagent, the epoxy resin opens the ring and reacts with silicon hydroxyl and epoxy groups on KH560 reagent through chemical bonding or physical interactions to produce an interlocking effect. 26,36 As a consequence, the IFSS at the interface is considerably improved after successful grafting of KH560.…”

“…Together with good resin impregnation, the bonding mechanisms of mechanical interlocking and chemical bonds between the fibers and resin are integrated to contribute to a stronger interface. 26,36 That is to say, the increased load transfer efficiency helps to significantly strengthen the textile composite material.…”

Effects of interphase regions and filler networks on the viscosity of PLA/PEO/carbon nanotubes biosensor

“…However, the advantages of nanocomposites depend on the dispersion of nanoparticles in the polymer matrix . Today's, the biodegradable polymers are attracting much interest, due to the increasing consumption of plastics and the limited amount of raw materials . Poly(lactic acid) (PLA) and poly(ethylene oxide) (PEO) are biodegradable and biocompatible polymers displaying good characteristics for biomedical applications .…”
