Expandable graphite/polyamide-6 nanocomposites

Polyamide-6 (PA-6)/graphite nanocomposites were prepared by melt blending, using a variety of graphites, including virgin graphite, expandable graphites and expanded graphite. The resulting nanocomposites were characterized by X-ray diffraction, thermogravimetric analysis, cone calorimetry, and tensile mechanical analysis. Nanocomposite formation does occur, as denoted by the nanometre dispersi...

Kinetic model for binding and hydrolysis

Glucosidase II is an enzyme involved in glycoprotein biosynthesis, releasing both a-1,3-linked glucose residues from the protein-linked oligosaccharide Glc2Man GlcNAc2-R in the processing of N-glycans. We studied the kinetic properties of the enzyme, purified to homogeneity and, for the first time, we have been able to demonstrate the occurrence of two active sites in this enzyme and to establi...

Multi‐jet electrospinning of polystyrene/ polyamide 6 blend: thermal and mechanical properties

Introduction Electrospinning process is broadly used to obtain membrane-like webs with submicron to micron fibers (Li and Xia 2004). Electrospun nanofibers, with its large surface area and multiple pores, can be used to construct unique functional nanostructures for composites, filtration membranes, biomaterials, and breathable textile fabrics (Greiner and Wendorff 2007; Li and Xia 2004; Pham e...

Blends of poly(vinylidene fluoride) with polyamide 6: interfacial adhesion, morphology and mechanical properties

The poly(vinylidene fluoride) (PVDF)/polyamide 6 (PA6) interfacial adhesion has been measured, and morphology and mechanical properties of the binary blends have been investigated. The lap shear strength of the PVDF/PA6 pair indicates a high interfacial adhesion, which is evidence for specific intermolecular interactions between the two polymers. Immiscibility of PVDF and PA6 has clearly been o...

Tribological and Mechanical Behaviors of Polyamide 6/Glass Fiber Composite Filled with Various Solid Lubricants

The effects of polytetrafluoroethylene (PTFE), graphite, ultrahigh molecular weight polyethylene (UHMWPE), and their compounds on mechanical and tribological properties of glass-fiber-reinforced polyamide 6 (PA6/GF) were studied. The polymeric materials were blended using twin-screw extruder and subsequently injection molded for test samples. Mechanical properties were investigated in terms of ...
