  • The project is targeted towards the development of an atomistic approach to help understand the size effects of superparamagnetic nano-particles on the macroscopic properties of composite polymeric materials. The emergence of nano-structured systems gives rise to both new expectations and new challenges, ranging from optimal design to applications. At the international level, the competition is particularly intense, especially regarding the development of new devices and tools for exploring and exploiting the unusual physical aspects of nano-structured materials in many technological fields, such as energy, electronics, biology etc. These developments are of great interest for tackling the more challenging human needs. However, the challenges bring us face to face with the problem in which the properties that are measurable and exploitable for the end user are the result of a complex sequence of elementary phenomena that traverse the hierarchical length scales within the material constituents. In the case of nano-structured materials, these scales integrate the atomic scales ( Ångström ) governed by the first principles, and conclude with the end user system (Centimeter). The direct consequence is that it is not possible to optimize engineering systems unless we integrate into the modeling, design and optimization chain the interactions that occur throughout the scales whenever possible. The engineering approach targeting new nano-based systems thus needs to be enriched by more physical approaches.

    In the case of nano-reinforced polymers particle size was found to be a major parameter leading to drastic stiffening effect. The origin of such enhancement was investigated by means of an atomistic approach. A binary system was characterized using a DREIDING force field on the LAMMPS molecular dynamics platform. Results derived from the atomistic approach were precious to understand the orignin of the stiffening effects.

    Mission

    The researcher task will be to help augment already developed approaches to handle the magnetic and / or piezoelectric properties in nano-reinforced polymers.

    Principal activities

    Therefore the researcher position will be meant to help reach the following objectives:

    Does particle size act on macroscopic material responses other than mechanical (size effect and electric, magnetic, piezoelectric, etc) and is there a critical size under which no effects, or more effects, are noticeable?

    How can the experimental approach be tailored by means of the length scale sensitive modeling approach?
