Researchers have developed a material that can be reshaped while retaining the properties of lightness, resistance and strength. It is also a repairable and recyclable material.

This compound has been developed by a team of researchers led by Ludwik Leibler, CNRS researcher at the Laboratoire “Matière Molle et Chimie” (CNRS/ESPCI ParisTech). This research has been published in the November 18 issue of the Journal Science.

Researchers used the materials, like epoxy resins, hardeners, catalysts, etc., which are available in industry and made a novel organic material made of a molecular network with original properties. This molecular network is capable of organizing itself under the action of heat without changing the number of cross-links between its atoms. This material changes from liquid state to solid state or from solid state to liquid state just like a glass and thereby behaves like pure organic silica. It is insoluble even at its glass transition temperature.

At room temperature, it behaves like a hard or soft elastic solids and in both cases it has the characteristics of thermosetting resins and rubbers presently used in industry.

It is not only inexpensive but also easy to produce and can be used in a large variety of industrial applications, like building, aeronautics, electronics and leisure sectors, which require the replacement of metals by lighter materials.
