Treated, mesoporous aggregates comprising a plurality of coated particles that comprise an inorganic oxide core having a surface area of about 50 to about 500 square meters per gram and a shell or coating consisting of an array of fluoroalkyl molecular chains covalently bonded to the core at a density of at least one chain per square nanometer. The aggregates are formed by the chemical attachment of fluoroalkyl-alkylsilanes after exposure to an alkylamine and followed by an extraction to remove any unbound organic material. The dense packing of molecular chains in the fluoroalkyl shell combined with a mesoporous structure imparts a very low surface energy, a very high specific surface area, and surface texture over a wide range of length scales. Such features are highly desirable for the creation of, for example, superhydrophobic and superoleophobic surfaces, separation media, and release films.

The present invention relates to the installation of floorcovering articles on chemically abated flooring surfaces and the composite article resulting therefrom. More specifically, the invention relates to a process for chemical removal of mastic, putty and/or paste material from a flooring surface. The process includes applying abatement chemical to the mastic material on the flooring surface to soften the mastic material and cause it to physically separate and release from the flooring surface, removal of the mastic material and abatement chemical, and the subsequent application of a barrier coating to the flooring surface. The barrier coating reduces and/or eliminates the migration of residual abatement chemicals into floorcovering articles thereinafter installed on the chemically abated flooring surface. The resulting composite article is comprised of a chemically abated flooring surface containing pores, at least one abatement chemical in said pores, a polymer-containing barrier material, and a floorcovering article.
