New polymeric materials with exceptional mechanical and thermal properties

New and innovative aspects

These new aramids and / or polymers reinforced with carbon nanofillers can be prepared in the form of a porous membrane, dense membrane, coating, fiber, etc., constituting materials with exceptional mechanical and thermal properties. Nano and microporous materials are made by adding an ionic liquid in the preparation process and its subsequent removal in a solvent, producing high-performance materials with a reduced density.

Main advantages of its use

• Simplicity of the manufacturing process. The porosity generation process is simpler, faster and more homogeneous than other techniques such as phase inversion or the use of supercritical CO2.

• Versatility, since it can be applied to both membranes and thicker materials (up to several mm).
• It is possible to control the porosity parameters based on the process conditions (quantity and type of ionic liquid used, mainly).
• The functionalization of the nano-fillers allows an optimal dispersion in the polymer.
• The porous structure notably improves the mechanical properties compared to dense polymers (without porosity). These specific properties (values relative to density) are superior in porous materials compared to dense materials.

Specifications

Aramids reinforced with nano-fillers are prepared by dispersing the functionalized nano-filler in a solution of the aramid, and subsequent removal of the solvent. These polymers can be prepared in the form of a porous membrane, dense membrane, coating, fiber etc. obtaining materials with exceptional mechanical and thermal properties. Nano and microporous materials are made by adding an ionic liquid in the preparation process and its subsequent elimination in a solvent, producing high-performance materials with reduced density.

Applications

These materials can be used as high-performance polymers in different applications, such as:

• Reinforcement in different structures
• High resistance textile fibers
• Flexible conductive materials
• Energy storage elements in electrochemical applications
• Filtration membranes and water purification.
