摘要： A self-healing polymer additive includes diene (e.g. butadiene, cyclohexadiene, pentadiene, tetrahydrofuron or their derivatives) and dienophile (e.g. maleic anhydride, maleamide, conjugated carbonyls or their derivatives etc.). One polymer includes tetrahydrofuron and maleimide. Furfurylamine 12 (1-10 gm) is diluted in acetone. Under an inert atmosphere an equivalent amount of granular maleic acid is added slowly, and the reaction is allowed to take place. Resulting maleamic acid precipitates. The maleamic acid product is separated, dried and purified by re-crystallization. The maleamic (1-5 gm) acid is dissolved in acetic anhydride along with a catalytic amount of sodium acetate. The resulting solution is heated for a few hours in 80-120° C. The precipitated final product is separated, purified and dried in a vacuum. The self-healing polymer is dissolved in a solvent, and self-healing molecules are cross linked and are mixed with a polymer matric for various applications such as coatings and structural materials.

摘要： Clay platelets are separated from an agglomeration of clay platelets by treating with cobalt acetate and leaving cobalt particles on the platelets. Carbon nanotubes are grown on the platelets at the cobalt sites, and the nanotubes separate platelets from the agglomeration. The separated platelets and nanotubes are acid cleaned. Intumescent fire retardant materials are chemisorbed on the clay platelets and nanotubes.
