Dear Colleagues,

Please see our recent article on toughening 3D printable resins with block copolymer additives:

Abstract

Distinct deformation mechanisms that emerge in nanoscale enable the nanostructured materials to exhibit outstanding specific mechanical properties. Here, we present superior microstructure- and strain-rate-dependent specific penetration energy (up to ∼3.8 MJ/kg) in semicrystalline poly(vinylidene fluoride-co-trifluoroethylene) (P(VDF-TrFE)) thin films subjected to high-velocity (100 m/s to 1 km/s) microprojectile (diameter: 9.2 μm) impacts.

1 Post-Doc Position TV-L E13 (m/f)

Colloids in polymer systems: Numerical studies and simulations

Description
The selected individual will lead the development, initial application and deployment of new modeling capability in the area of thermoplastic packages. The initial focus is on developing best in class material models across a range of polymers. This material modeling capability will be leveraged globally for a broad range of packaging model applications (blow molding, parison / preform optimization, empty and full bottle interaction with packing lines, etc.)

A single strand of polymer is a chain of a large number of monomers.  The monomers are joined by covalent bonds, and two bonded monomers may rotate relative to each other.  At a finite temperature, the polymer rapidly changes from one configuration to another.  When the two ends of the polymer are pulled by a force, the distance between the two ends changes.  The polymer is known as an entropic spring.
