Phase-Separation Processes in Polymer-Solutions in Relation to Membrane Formation

This paper reviews recent studies conducted on carbon nanotube/polymer composites. Carbon nanotubes are promising new materials for blending with polymers with potential to obtain low-weight nanocomposites of extraordinary mechanical, electrical, thermal and multifunctional properties. The size scale, aspect ratio and properties of nanotubes provide advantages in a variety of applications, including electrostatically dissipative materials; advanced materials with combined stiffness, strength and impact for aerospace or sporting goods; composite mirrors; automotive parts that require electrostatic painting and automotive components with enhanced mechanical properties. The various processing methods for producing these nanocomposites are discussed, in particular melt mixing, solution processing and in-situ polymerization. Some key results are summarized, relating to the mechanical, electrical, thermal, optical and surface properties. Finally, the challenges for the future are discussed in terms of processing, characterization, nanotube availability, nanotube tailoring, and the mechanisms governing the behavior of these remarkable nanoscale composites.

A review of vapor grown carbon nanofiber/polymer conductive composites

Poly(methyl methacrylate) (PMMA) was melt mixed 30:70 into polystyrene (PS) with and without symmetric P(S-b-MMA) diblock copolymers The molecular weight of the components was varied After 5 min of shear mixing, the PMMA was dispersed into roughly spherical, submicron particles Particle size was measured by light scattering and transmission electron microscopy As little as 1% copolymer led to a significant reduction in PMMA particle size, although larger amounts were needed to make the particles stable to annealing (180 °C for 15 min) The principle role of block copolymers in controlling morphology appears to be in preventing coalescence Preventing dynamic coalescence leads to size reduction, while preventing static coalescence results in stability or compatibilization We estimate that less than 5% of the interface needs to be covered to prevent dynamic coalescence while ∼20% is necessary to impart static stability Mobility, critical micelle concentration, and molecular weight of the block copolym
