Abstract:
1. A method for making a polymer composite comprising: mixing, a thermosetting polymer precursor, and 0.01 to 30 wt % of a derivatized nanoparticle based on the total weight of the polymer composite, the derivatized nanoparticle including functional groups comprising carboxy, epoxy, ether, ketone, amine, hydroxy, alkoxy, alkyl, aryl, aralkyl, alkaryl, lactone, functionalized polymeric or oligomeric groups, or a combination comprising at least one of the forgoing functional groups, wherein the thermosetting polymer precursor, derivatized nanoparticle, and functional groups are selected such that a variability in tensile strength, percent elongation, and average modulus for the polymer composite is less than the variability of these properties where an underivatized nanoparticle is mixed with the thermosetting polymer precursor in place of the derivatized nanoparticle.
