Interaction sheets—solvent particles

In addition to excluded volume, the conformation and dynamics of a sheet can be controlled by introducing (intrasheet) interactions among its particles as well as interactions and constraints with other constituents in the host matrix. The physical properties of the sheet (clay platelet or tethered membrane) depend on the type of interaction with the underlying matrix (e.g., solvent), concentration, temperature, and a host of external and internal parameters. 

In addition to excluded volume, solvent particles and polymer chains interact with sheets with a short-range square-well pair potential. The interaction energy of a particle (representing particle, chain, or sheet) is described by... 

Various compounds have been prepared by solvothermal reactions metals, metal oxides, chalcogenides, - ° nitrides, - -" phosphides, open-framework structures, - oxometalate clusters, - organic-inorganic hybrid materials, - - and even carbon nanotnbes. - Most of the solvothermal products are nano- or microparticles with well-defined morphologies. The distribution of the particle size of the prodnct is nsnally qnite narrow, and formation of monodispersed particles is freqnently reported. - When the solvent molecules or additives are preferentially adsorbed on (or have a specific interaction with) a certain surface of the products, growth of the surface is prohibited and therefore products with unique morphologies may be formed by the solvothermal reaction. - - Thus nanorods, wires, tnbes, and sheets of various types of products have been obtained solvothermally.
