“…Different techniques are in use to characterize the surface of the adsorbents. To investigate the behaviour of porous silica coated with siloxane polymers, Gilpin et al [1] used nitrogen adsorption technique for surface area and porosity of silica and polymer coated silica; and high-resolution thermo gravimetric technique for thermal behaviour of silica. They found a uniform layer of siloxane polymer on silica surface.…”

“…An earlier study utilizing IR spectroscopy [13] documented that the siloxane polymer forms hydrogen bonds to the silica surface through the cyano group of the polymer. The adsorption properties of these coated materials are also reported [14]. We have extended our investigation to further characterize the physisorbed materials by one-and two-dimensional NMR spectroscopy.…”

“…Silica particles have been modified by adsorption of polyacrylic acid [125], polyacrylamide [133], polyethylenoxide [136][137][138], or siloxane polymers [139] such as polydimethylsiloxane (PDMS) [126] and oligo(dimethylsiloxane) [81]. The extent of adsorption depends on various factors: the structure and molecular weight of polymer [136,138], solvent [138,140], pH [125], or temperature [125,132,138,141].…”

The incorporation of organic compounds onto the surface of nanoparticles (NPs) differs from the same reactions carried out on macroscopic surfaces in that the former are characterized by surfaces energies much higher than the latter. Consequently, surface stabilization mechanisms of NPs are very active, and among them NP self-aggregation is the first and most important. In NP surface modification, the ability of the experimental conditions to destroy self-aggregation will determine the extent to which the NP surface is modified and so, the modified NP nature. A second consequence of the high-surface free energy is the NP surface avidity to interact chemically or physically with other compounds: NPs readily adsorb water, gases, vapors, or other higher molecular weight substances, and in the particular case of hydroxylated NP, chemical reactivity is both high and rich. This chapter will deal with the surface modification of silica, sepiolite, and polysaccharides. Experimental strategies, resulting organo-NPs, their structure and properties, and frequent uses and applications of them will be reviewed.
