Abstract

A method of producing modified buoyancy bodies and particulates involves pre-treating one or more substrate surfaces with acid to activate hydroxyl groups, rinsing the substrate surfaces to remove excess acid, functionalizing the pre-treated substrate surfaces with hydrophilic chemical moieties to provide hydrophilic functionality to the substrate, and attaching chemicals, materials, and/or fillers to the substrate surfaces sequentially to produce bodies and/or particles having modified functional attributes.
