A method for transporting a material (which may be a viscous fluid) in a conduit defined by a conduit-defining surface comprises: flowing a first fluid and a second fluid in a flow direction within the conduit; contacting the first and second fluids to one another at a contact region to thereby facilitate a reaction creating a reaction product in an interface region that extends downstream from the contact region, wherein the reaction product is an elastic-solid; and transporting the material in the flow direction within the conduit. At locations downstream of interface region, the reaction product creates a barrier between the viscous fluid and the conduit-defining surface.

The present invention relates to a vinyl chloride-based polymer showing high viscosity properties in a low shear region and showing viscosity and stress decreasing properties in line with the increase of a shear rate, a method for preparing the same, and a plastisol comprising the same. Since the vinyl chloride-based polymer comprises a saponified emulsifier in a specific ratio, high viscosity properties may be shown in a low shear region, and Bingham fluid flow properties may be shown, by which viscosity and stress decrease in line with the increase of a shear rate.

The present invention relates to a method and an apparatus both for producing molecular assemblies of an amphiphilic block polymer. The method of the present invention includes: applying a polymer solution (45) containing an amphiphilic block polymer and a solvent in a layered shape on a planar base member (11) in a film forming part (40); forming a polymer film on the base member (13) by removing the solvent from the coated layer of the solution in a drying part (30); and producing molecular assemblies by bringing the polymer film into contact with a water-based liquid (55) in a molecular assembly forming part (50). The amphiphilic block polymer has a hydrophilic block chain and a hydrophobic block chain. The hydrophilic block chain preferably has 20 or more sarcosine units, and the hydrophobic block chain preferably has 10 or more lactic acid units.

A degradable polymeric nanotube (NT) dispersant comprises a multiplicity of NT associative groups that are connected to a polymer backbone by a linking group where there are cleavable groups within the polymer backbone and/or the linking groups such that on a directed change of conditions, bond breaking of the cleavable groups results in residues from the degradable polymeric NT dispersant in a manner where the associative groups are uncoupled from other associative groups, rendering the associative groups monomelic in nature. The degradable polymeric nanotube (NT) dispersant can be combined with carbon NTs to form a NT dispersion that can be deposited to form a NT film, or other structure, by air brushing, electrostatic spraying, ultrasonic spraying, ink-jet printing, roll-to-roll coating, or dip coating. The deposition can render a NT film that is of a uniform thickness or is patterned with various thicknesses. Upon deposition of the film, the degradable polymeric nanotube (NT) dispersant can be cleaved and the cleavage residues removed from the film to yield a film where contact between NTs is unencumbered by dispersants, resulting in highly conductive NT films.
