Periodic Report Summary 2 - NANOTOUGH (Nanostructured toughened hybrid nanocomposites for high performance applications)
Publishable summary:
NANOTOUGH objectives and goals
NANOTOUGH is a European framework project that focuses on developing tough plastic materials using nanotechnology.
Nanocomposites are emerging new materials that promise improved properties, but in practice, it has been difficult to translate existing knowledge on nanotechnology into tangible products. NANOTOUGH's objective is, in addition to basic research, to remove the technical barriers so that nano-composite materials can be used commercially.
The basic objective is to obtain a deeper understanding of the interfacial structure of nanocomposites within a polyolefin matrix. This knowledge will enable realisation of the great performance potential of these materialise through development of novel multiphase and hybrid nanocomposites. This knowledge will facilitate commercialisation of polymer nanocomposite materials with superior properties that will lead to development of new products.
To meet this objective, we aim to improve the stiffness of polyolefin nanocomposites while not only maintaining but also improving the toughness of the matrix considerable. The technical objective is to optimise and, through novel interface design, to develop new cost effective hybrid (nanofiller-fibre) nanocomposites as an alternative to heavily filled polymers and expensive engineering polymers and fulfil industry requirements for high-performance materials in high-tech applications.
Project activities
WP1: Materials - interface design
A major activity in this work package is the synthesis and use of functionalised block co-polymers to induce and enhance the intercalation and exfoliation of nanoparticles in polyolefines and to improve their stiffness and impact strength.
WP2: Structure and composition analysis
State-of-the art characterisation techniques, like Focused ion beam-scanning electron microscope (FIB-SEM), high-resolution Environmental transmission electron microscopy (ETEM), Wide angle X-ray scattering (WAXS) and (Small angle X-ray scattering) SAXS are carried out to study the structures at nano-scale level particularly related to the interphase.
WP3: Flow and dispersion mechanisms:
The objective of this WP is to obtain increased knowledge on the effect of various parameters on dispersion process by means of rheological measurements including rheo-X-ray techniques
WP4: Properties at service conditions
The activity is concentrated on experimental analysis of the visco-elasto-plastic response of the nanocomposites, development of constitutive models for the mechanical behaviour of hybrid nanocomposites and analysis of the effects of filler (chemical structure, type, concentration) and compatibiliser (chemical structure, concentration, mixing conditions) on the mechanical behaviour of hybrid nanocomposites
WP5: Implementation
A major activity in this work package is preparation for productions tests using various compounding techniques. Furthermore, materials will be processed and shaped into selected automotive and aerospace parts.
WP6: Dissemination and exploitation of results
The work is concentrated on maximisation and early-stage exploitation of the project results and successful market implementation
WP7: Management:
Management of the project and coordination to other related research activities
Grafted nanoclays
Project outcomes:
So far, the outcomes of the project are improved models for nanocomposites, increase in several mechanical properties like stiffness, strength, creep resistance, impact properties and more. Furthermore, important knowledge has been gained concerning chemical modification and processing.
Perspectives
The perspective of the current work is to turn upside down the construction of a number of well-known products where metals or plastics are used today in cars or aircrafts. As an example, car components like spare wheel well and structural parts like bumper carriers are developed:
