Abstract
The present invention relates to cross-linked polyolefin aerogels in simple and fiber-reinforced composite form. Of particular interest are polybutadiene aerogels. Especially aerogels derived from polybutadienes functionalized with anhydrides, amines, hydroxyls, thiols, epoxies, isocyanates or combinations thereof.
Claims18
An aerogel material comprising a cross-linked polyolefin structure wherein the cross-linkages is a result of reactions between hydroxyl, amine, epoxy, anhydride, thiol or isocyanate groups in the polyolefin and hydroxyl, amine, epoxy, anhydride, thiol or isocyanate groups of a hardner.
A method of preparing an aerogel material comprising the steps of:
- dissolving an amount of a polyolefin in a suitable solvent;
- adding an amount of hardner to the polyolefin solution;
- adding a catalyst suitable for cross linking, to the solution;
- allowing the solution to form a gel;
- and
- drying said gel.
