LIGHT WEIGHT STRUCTURAL MATERIALS

摘要

Functionalized microspheres for being dispersed in matrix materials to reduce the density and weight of the materials may be configured to include a covalently bound surface component which is configured to covalently bond with the matrix material so that when combined with the matrix material a strong, light-weight matrix material may be produced.

1. Functionalized hollow microspheres for reducing the density of structural matrix materials, the functionalized hollow microspheres comprising:
at least one hollow microsphere comprising at least one anchoring group covalently bonded to a surface of the microsphere; at least one functional group configured to covalently bond with the structural matrix material; and a linking component covalently bonding the at least one anchoring group with the at least one functional group, wherein the linking component is selected from linear, branched, cyclic, substituted, unsubstituted, saturated, and unsaturated C1-C50 carbon-based chains, and combinations thereof.
