Resumen:
Un equipo de investigación de una universidad italiana con experiencia en ingeniería de fabricación y materiales ha desarrollado una resina termoestable reciclable. Esta resina ofrece las mismas propiedades de durabilidad y resistencia que los plásticos termoestables correspondientes no reciclables pero, a diferencia de ellos, puede reutilizarse. La resina está hecha de una nueva clase de polímeros termoestables, poli(hexahidrotriazina)s. Estas estructuras se disuelven en un ácido fuerte, rompiéndose la cadena de polímeros en monómeros para volver a montarse y crear nuevas configuraciones y productos. El equipo de investigación busca universidades, institutos de I+D y pymes con el fin de establecer acuerdos de cooperación en materia de investigación.

Recyclable thermoset resin: an advantageous alternative between thermoplastics and thermoset polymers.
Summary:
An Italian university research team has expertise in the field of materials and manufacturing engineering. The technology offered is a recyclable thermoset resin. This product has the same properties of durability and strengthens of the corresponding unrecyclable thermoset plastics, but differently from them can be used more than once. The team is looking for universities, R-Y-D institutes and SMEs to reach a research cooperation agreement.
Description:
The Italian university research team has expertise in the field of materials and manufacturing engineering.
The technology offer is recyclable thermoset resin.

Plastics are divided in two categories: thermoplastics and thermoset plastics.
Thermoplastics can be heated and shaped many times, and so they are characterized by an elevated flexibility and are generally recyclable, in compliance with environmental and costs reduction issues.
On the contrary, thermoset plastics can only be heated and shaped once, retaining their shape and configuration even under intense heat and pressure. They are characterized by an high level of resistance, toughness and durability, but they are not recyclable. Both materials find many applications in different fields of manufacturing according to their specific properties.

The research team offers a recyclable thermoset resin made with a new class of thermosetting polymers, the poly(hexahydrotriazine)s (PHTs). These structures can be dissolved in strong acid breaking the polymer chain into monomers that can further be reassembled into new configurations and products.

Because of this property, they could represent an alternative to the existing thermoplastics and thermoset plastics combining together the advantages of both: flexibility and recyclability of the former with strength and durability of the latter. PHTs are a new cutting-edge technology; their discovery was officially announced in 2014. Although many critical advances have already been made toward their production, there are several challenges to overcome before PHT could be put on the market.
In fact, at the present stage these structures can feature very good thermal stability (T > 300°C) and stiffness (E ~ 14 GPa), but limited toughness and ductility, and their production is still a rather expensive process.
Research and development activities are carried out in order to engineering the formulation of PHTs, specifically to enhance their mechanical properties and reduce their brittleness.

The research team proposes a research cooperation agreement in order to carry out jointly R-Y-D activities on this technology.
Partners sought are universities, R-Y-D institutes and SMEs with expertise in innovative materials.


Advantages and Innovations:
The recyclable thermoset resin has good thermal stability and stiffness.
For these characteristics, the development of high performance PHTs and their composites with hybrid nano-fillers is of utmost practical relevance, as this class of materials could join high performance typical of thermosetting polymers (strength and durability) together with easy routes to their de-polymerization for reprocessing and recycling purposes.

PHTs could open reliable patterns to the fabrication of environmental-friendly and industrially sustainable end-goods made from thermosetting but fully recyclable/reusable polymers.
Moreover, the reusability of PHTs through their decomposition in acid solution will produce a notable economic advantage with respect to the previous reduction features at the end of life cycle (reduction to powder, at least 1/2 order of magnitude less than the original economic value).

Partner sought

Type and Role of Partner Sought:
The research team is looking for universities, R-Y-D institutes or SMEs with expertise in the field of manufacturing, nanotechnologies and innovative materials.
The partnership considered is a research cooperation agreement.

The partnership, depending on the reciprocal resources and expertise, could have the objective to directly and autonomously develop further steps in the co-research and co-development work, or even the creation of a solid and well-established consortium to participate to dedicated calls for tender both at national and at European level.

The research team can offer its know-how in the engineering of PHTs formulation, with research and development activity into the design, manufacturing and evaluation of performance of work pieces (mechanical properties enhancement and brittleness reduction).
