Tittle:
High performance nano-reinforced resins for barrier coatings
Summary:
Research team from an Italian university has developed nano-reinforced resins with bi-dimensional nano-fillers. This technology features barrier properties against aroma, gas, vapour, erosion, corrosion and scratch. The proposed technology is applicable for protective coating systems in the field of automotive, furniture, wall covering, flooring and photovoltaic. The research team is seeking industrial partners for technical cooperation agreement and it can offer a prototype for demonstration.
Description:
The Italian research team is active in the field of technology and manufacturing systems. he research activities concern:
-new manufacturing technologies by fluidized bed;
-application of hard coatings and evaluation of tribological properties;
-manufacturing process of metal foams;
-processing by laser technology;
-coatings and organic-inorganic materials and identification of relationship among material-process-product.

The nano-reinforced resin with bi-dimensional nano-fillers can lead to composite materials, which might express a huge potential in terms of mechanical, chemical and physical performance. However, dispersion of nano-platelets inside the resin can be extremely troublesome and compromise the final performance of the composite material.

The offered technology represents a simple and effective route to overcome the troublesome dispersion of nano-platelets inside a variety of resins. Nano-fillers, such as cellulose fibrils, solvent vaporization and flask rotation induce alignment of nano-platelets expanding d-spacing of resins. The resulting nano-platelets added with resin pre-polymers and curing agents can be deposited on a number of different substrate.
The resulting materials will benefit from the concurrent properties of each filler, thus getting to final results not achievable by using individually any single constituent. These synergistic effects and the good dual dispersion allow protective coating to be applied with high performance in the following fields:

· Decorative applications (automotive and furniture manufacture, wall covering and flooring):
-Transparent protective coatings;
-Nano-reinforced coatings;
· Functional applications (automotive and photovoltaic):
-Scratch and wear resistant coatings;
-Anti-erosion-coatings;
-Anti-corrosion coatings;
-Barrier properties.

The proposed nano-reinforced resins offer technical properties in terms of reduction of hardiness, improved scratch resistance and wear resistance, enhanced shelf time and curing temperature.
At the present stage, the research team use the university lab-facilities to produce small batches of the mentioned formulations.

The scope of the technical cooperation agreement is to design and develop solutions to produce large amount of materials in reasonable processing time. This goal could be pursued by an industrial partner able to scale up the amount of material to produce. The partner sought it is expected to ensure the availability of the following instruments and equipment:
· reactors for the customization of the fillers;
· reactors for the dispersion of the filler in the matrix;
· equipment for the concentration of the formulations.

On the one hand, the industrialization of the formulations would be require the implementation of an ad-hoc production line and related necessary investments. On the other hand, running of this production line would require involvement of high-qualified technicians thus generating an high employment potential.
Moreover, since the proposed nano-reinforced resins belong to the class of specialty coatings, they are highly customized materials, which are not required to comply with the strictest environmental regulations. Once the materials are formulated and packaged they can be considered safe for the operators and the working environment.

By an energetic point of view, it is possible to emphasize that this kind of materials are highly protective against the surrounding environment and external loads. Accordingly, it can be extended by far the useful lifespan of the item on which they are applied to. This can have a relevant impact on the lifecycle of the item being protected.
Advantages and Innovations:
The innovation of the proposed nano-reinforced resin relies on using two types of reinforced materials to yield good dual dispersion and synergistic effects.
The offered technology allows overcoming the problematic dispersion of nano-platelets using nano-fillers, polymers and curing agents.
The proposed technology can lead to composite materials, which might express a huge potential in terms of mechanical, chemical and physical performance. Gas molecules are forced to traverse tortuous path to arrive at other side of barrier ¿lm, thus reducing the overall permeability of the material. Nano-composite forms a robust layer achieving protective coatings with outstanding mechanical, physical and chemical performances. In addition, this coating also features exceptional barrier properties against aroma, gas and vapour.
In comparison with other prevailing technologies, the proposed nano-reinforced resins offer the following technical properties:
· reduction of hardness (from pencil 9H to pencil 7H);
· improved scratch resistance and wear resistance;
· enhancement of shelf time (from 6 months to 2 years);
· low curing temperature.

Partner sought

Type and Role of Partner Sought:
The Italian research team is interested in technology transfer with Small and Medium-sized industrial companies, active in fields of chemicals and/or resins processing.
The research team is seeking partners able to implement the scale up of the lab-based formulations.
The goal of the cooperative activity is primarily the possibility to achieve large batches of the material formulation for significant industrial tests. This would allow investigating the suitability of the materials in application fields very close to the industrial one. This could also allow attracting potential customers.
The contribution expected from the partner is the investment in new technologies (if not available). In addition, the partner is expected to enhance its know-how by means of closer analysis of the products and of their related potentialities. With this regard, the research group is ready to be aside to the industrial partner in the implementation of the demonstration facilities on a pre-industrial scale.
The type of partnership considered is technical cooperation agreement.
