Smart polyurethane alloys for components having electrical and thermal functional gradients

Obiettivo


Expected deliverables were:
- Brand of polyurethane susceptible to be developed;
- Brand/s of powders which are capable to make the above mentioned brand of polyurethane conductive (that is to say, lowering resistivity from 1012 Ohm-cm to 105-104 Ohm-cm).
Experimental injection system implementing the injection process with doped powders, as well as the system for properly disposing the powders over a predefined 2D or 3D pattern (functional gradient process).
Industrial workpieces injected and doped through the above mentioned process, and showing the above mentioned conductivity performances in the doped sections of the pattern, using them for practical applications.

All the above mentioned expected deliverables have been achieved, and more. In particular:
- The resistivity has been lowered down to 103 Ohm-cm, in industrial workpieces, and down to 100 Ohm-cm in test samples, thus opening up further industrial exploitation possibilities (EMI screening) than initially envisioned;
- Alternative techniques, such as carbon-fiber doping, have been investigated.
Objectives and content
The utilisation of plastic materials in industrial
manufacts has been experimenting a very sharp growth in
the last decades. This is true, in general, for all
kinds of plastic materials, which have seen their fields
of application gradually increased from simple, consumeroriented objects up to large and complex workpieces, with
elevate structural characteristics of mechanical and
thermal resistance. One typology of manufacts, however,
has so far been unable to fully profit of the large-scale
of plastic materials, this typology is, in general,
constituted by all the manufacts and workpieces requiring
high electrical and/or thermal conductivity, in order to
perform their functional role. This makes the
application of plastic materials, other than for
insulating purposes, quite difficult to apply to a large
spectrum of products and market sectors.
It is evident that the availability of a plastic material
with good electrical and/or thermal conductivity
performances could open completely new possibilities for
the utilisation of plastic materials, up to configure
itself as a revolutionary innovation in the fields of
materials technology, which could lead to very relevant
improvements in the characteristics (weights, costs,
etc.) of electrical devices.
The current project proposal has just the purpose of
developing a variety of plastic material provided with
high electrical and thermal conductivity, for use in the
injection mould of industrial plastic workpieces. This
proposal, which is the result of extensive and in-depth
preliminary work performed by one of the partners, work
which has ascertained the theoretical feasibility of this
development, will have the objective of both developing
the material above mentioned, (which will be obtained, in
general terms, through the doping with metallic powders
of a newly configured, polyurethane-based plastic
material), and the process through which this material
will be usable, thus resulting, at project's end, into
the development of actual workpieces suitable for
industrial use.
The project is carried over by an industrial consortium
composed by some of the most representative European and
World realities in the development and processing of
plastic materials, as well as by some leading European
research institutes in plastic technologies. The
partners are extremely determined to pursue the
commercial exploitation of project results, and have the
capabilities to perform this exploitation on a worldwide
basis.
