Project Objectives

The field of construction materials is one of the main industrial branches with increased interest to a large number of producers, manufacturers and users. One of the main issues in the construction units is the resistance in the corrosion. The huge economic impact implicated with corrosion issues and the unpleasant consequences ensuing, imposed an urgent need to develop methods and techniques, both in predicting and assessing the risk of corrosion, and the corrosion protection of concrete and metals.

Nowadays, in order to overcome the corrosion issues, sealants are usually applied for the prevention of the ingress of moisture in the body of the construction. The main property of these sealants is that they do not allow water to penetrate the construction body. Depending on their chemical composition they are divided into: asphalt compounds, plastic and elastomeric compounds, bicomponent materials, silicone materials and minerals.

Presently, the scientific and technological advances in the field of construction materials have resulted in the development of new environmentally friendly and energy-saving materials and application methods, which require special knowledge and experience. More specifically, the progress in nanotechnology offers new possibilities in the production of novel materials for highly demanding applications. It is now possible to create new multiphase nanomaterials having better properties than the traditional ones.

To this direction, the objective of the project is the synthesis of advanced hybrid nanomaterials for the protection and the sealing of the surfaces. The ultimate goal is to use the final products of the project for the manufacture of novel sealants with properties better than that of the existing materials.

More specifically, under this project, will be held:

  • Synthesis of acrylic emulsion of core-shell type.
  • Synthesis of hybrid acrylic / polyurethane emulsion of core-shell type.
  • Full characterization of molecular, morphological, mechanical and sealing properties of the produced hybrid nanomaterials.
  • Implementation and testing of the produced hybrid nanomaterials in various types of surfaces under real conditions.
  • Transfer of technical production reactors in pilot and industrial scale.

The fulfillment of the above objectives is of particular importance for the two industrial organizations involved in this project, since the production of new type, nanotechnology based materials is expected to offer great advantages over competitors in the highly demanding industry of construction materials. More specifically, it is expected that the produced materials will exhibit improved protection and waterproofing properties in comparison with that of the existing materials. It is expected that these new materials will be included in the product line of the two companies, thus enhancing their competitiveness by creating a new market in Greece and developing new activities in an even wider area.

Another important target of this project is these new materials to be more environmentally friendly and replace other that contain solvents and various additives (stabilizers and surfactants) which are harmful to the environment and the people who daily come into contact with them. Another important aspect of the project is the new hybrid nanomaterials, generated within the project lifetime, to be compatible with the new regulations on energy performance of buildings, as they will reflect the incident solar radiation on buildings and also offer better insulation due to the more efficient sealing. In this way, the project will also contribute to the energy saving issues.
