Potential of ball milling to improve clay dispersion in nanocomposites

Epoxy-Clay Nanocomposites: Dispersion, Morphology and Performance

The exfoliated nanocomposite is of particular interest because it maximizes the interactions between polymers and clays, and thus it should result in dramatic improvements in mechanical and physical properties. However, it seems to be very difficult to exfoliate organoclay in epoxy resins. Organoclay is always aggregated on the micro-scale in epoxy resins with conventional dispersion methods. B...

Rubber Clay Nanocomposites

Clay-fulleropyrrolidine nanocomposites.

In this work, we describe the insertion of a water-soluble bisadduct fulleropyrrolidine derivative into the interlayer space of three layered smectite clays. The composites were characterized by a combination of powder X-ray diffraction, transmission electron microscopy, X-ray photoemission and FTIR spectroscopies, and laser flash photolysis measurements. The experiments, complemented by comput...

Application of Nano-Particles of Clay to ‎Improve Drilling Fluid

   Drilling fluids are an essential component of the rotary drilling process used to drill for oil and gas on land and offshore environments. The injection of this nano particle into drilling fluid increases the viscosity levels fluids. In these experiments, the rheological properties of the fluid including apparent viscosity (AV), plastic viscosity (PV), yielding point (YP), mud c...

Natural rubber-clay nanocomposites

The mechanical properties of non-vulcanized natural rubber and dialyzed natural rubber-clay nanocomposites have been studied by uniaxial deformations to evaluate the reinforcement efficiency of the clay. We show that while non-rubber molecules contribute to auto-reinforcement, removal of these molecules improves significantly the performance of clay as reinforcement agent. These mechanical prop...
