Shi, Xiaotao; Wu, Jianxun; Zhen, Xinping; Xie, Haisheng; Xiong, Chunzhu

In this study, a series of styrene-b-ethylene-co-butylene-b-styrene copolymer (SEBS)/polypropylene (PP)/oil blends with different kinds of oil composition was developed through melt blending. The effect of oil with different composition and properties on its phase equilibrium and “redistribution” in multiphasic SEBS elastomer was systematically studied for the first time. Moreover, an…

Dielectric and flash DSC investigations on an epoxy based nanocomposite system with MgAl layered double hydroxide as nanofiller

Szymoniak, Paulina; Li, Zhi; Wang, De-Yi; Schönhals, Andreas

Nanocomposites based on MgAL layered double hydroxides (LDH) and an epoxy resin were prepared and investigated by a combination of complementary methods. As epoxy resin Bisphenol A diglycidyl ether (DGEBA) was used with Diethylenetriamine as curing agent. The LDH was modified with taurine, which acts as an additional crosslinking agent…

Construction of Dual Orientation Crystalline Structure in Poly(vinyl alcohol)/Graphene Oxide Nano-Composite Hydrogels and Reinforcing Mechanism

Meng, Yeqiao; Zhao, Xiaowen; Ye, Lin

Oriented poly(vinyl alcohol) (PVA)/graphene oxide (GO) nanocomposite hydrogels with different draw ratios were prepared by stretching during a freezing/thawing process. The PVA/GO samples with a draw ratio of 200% had significantly enhanced mechanical properties by formation of a microfibrillar structure, while the tensile strength and compressive modulus respectively reached as…

Morphology and ionic conductivity relationship in silk/cellulose biocomposites

Blessing, Bailey; Trout, Cory; Morales, Abneris; Rybacki, Karleena; Love, Stacy A.; Lamoureux, Guillaume; O’Malley, Sean M.; Hu, Xiao; Cruz, David Salas-de la

The relationship between morphology and the ionic conductivity of polysaccharide–protein bio-electrolyte membranes is explored in this study. Structural proteins and polysaccharides form hydrophobic and electrostatic interactions, and the resulting matrices can exhibit novel and useful properties. However, transforming these natural biomacromolecules from their native state to a more usable form…

Simultaneously enhancing of wear-resistant and mechanical properties of the thermoplastic polyurethane (TPU) is important for its wider application. Herein, fluorinated graphene (FG) was proposed and respectively functionalized by two amine-terminated molecules: aliphatic poly (oxypropylene) diamine (D230) (compatible with soft segment (SS) of TPU), and aromatic phenylamine (PA) (compatible with…

Self-healing materials have attracted considerable attention because of their improved safety, lifetime, energy efficiency and environmental impact. Supramolecular interactions have been extensively considered in the field of self-healing materials due to their excellent reversibility and sensitive responsiveness to environmental stimuli. However, development of a polymeric material with good…

The high mechanical performance of common structural materials (e.g., metals, alloys, and ceramics) originates from strong primary bonds (i.e., metallic, covalent, ionic) between constituent atoms. However, the large formation energy of primary bonds requires high temperatures in order to process these materials, resulting in significant manufacturing costs and a substantial…
