Melt processing involves an interplay between fluid mechanics and heat transfer in rheologically complex liquids, and taken as a whole it is a nice example of the importance of coupled transport ...

Take the tangled spaghetti-soup of a polymer melt and stretch it: the immediate response is like that of an elastic network, as the polymers are forced to deform through their mutual entanglements.

Description: solvent resistance, through the combination of "low crystallinity" with "high hydrogen bonding strength", which are traits that are ordinarily in conflict, this new material realizes ...

This produces a granular, sticky material in which each salt particle is coated with a thin layer of polymer melt that is easily oxidized. “We increase the effective surface area of the polymer ...

What if we could invent materials that can repair themselves when damaged? Polymer molecules in various states – solid, melt, solution – are susceptible to covalent bond changes in response to ...

Polymer characterization capabilities in the laboratory include dilute solution viscosity, Gel Permeation Chromatography (GPC) and melt flow index. The core equipment in this lab include: ...

Electrospinning operates on a straightforward principle involving a high-voltage electric field applied between a droplet of polymer solution (or melt) held by a syringe and a grounded collector. The ...

1 Common polymer blend preparation methods include solution blending, graft copolymerization, melt mixing, latex mixing, and synthesis of interpenetrating polymer networks (IPN). 3 The development of ...

There are greater intermolecular forces between the long chains compared with smaller simple molecules. This means that polymers have a higher melting point than many other organic molecules.
