20100010119 | Corrosion-Resistant Epoxy Nanocomposite Coatings containing Submicron Emeraldine-Base Polyaniline and Organomodified Montmorrilonite - Disclosed is a method of preparation of corrosion-resistant epoxy coatings. The coating composition contains two main corrosion resistant factors: The first one was Eemeraldine-Base polyaniline (EB-PANi), dissolved in the aminic hardener of epoxy. The other one was montmorrilonite clay, dispersed or exfoliated in the base component of epoxy resin. The hardener composition was prepared via dissolution of EB-PANi in functional amines like 3-(aminomethyl)-3,5,5-trimethylcyclohexan-1-amine adopting sonication and nanoscale filtering methods. The base component was prepared via gradual charging of MMT clay in epoxy resin via high-shear mixing plus sonication method. The morphology of the coatings during different stages of preparation was studied by optical microscopy and scanning electron microscopy and TEM. The corrosion-protective performance of the resultant coatings was evaluated by electrochemical impedance spectroscopy and salt spray tests. The results were compared with those of conventional epoxy zinc-chromate and neat resin coatings. Superior corrosion resistance was achieved via dissolution of 0.5-2.5 wt % of EB-PANi in the aminic hardener and 2-4 WT % of organomodified MMT in base component of coating. | 01-14-2010 |

20120165432 | SELF HEALING POLYMER MATERIALS - The present invention generally relates to self healing polymer materials comprising thermoset and thermoplastic polymers. The present invention also relates to a method of manufacturing self healing polymer materials, methods of post-curing and healing the self healing polymer materials, composite materials comprising self healing polymer materials and methods of preparing the composite materials. In an attempt to develop improved structural materials, polymers and polymer materials have been identified that can be used in materials to act as self healing agents to repair structural damage occurring in the materials. The self healing polymer materials that have been identified are capable of being healed under post-curing or healing conditions. | 06-28-2012 |
20120277349 | FLAME RETARDANT AGENTS AND FLAME RETARDANT MATERIALS COMPRISING THE SAME - Disclosed is a flame retardant agent, including a nitrogen-based lignin formed by reacting 1 part by weight of lignin, 0.8 to 2.4 parts by weight of a nitrogen-containing compound, and 0.3 to 0.9 parts by weight of an aldehyde under an alkaline condition. The flame retardant agent can be added to thermoplastic or thermosetting resins to form flame retardant materials. | 11-01-2012 |
