  Objects of the present invention are to provide a composition which can easily give cured products enriched with hydrophilic groups at the surface, and a composition which can give cured products while ensuring that the surface is enriched with hydrophilic groups which are hardly concentrated at the surface by conventional methods; to provide cured products obtained from such compositions; to provide a composition which is suited for producing cured products having high and long-lasting hydrophilicity and also having high surface smoothness; and to provide a cured product obtained from the composition. A monolayer film is fabricated which includes a crosslinked resin obtained by polymerizing a composition including a compound (I) having at least one hydrophilic group selected from anionic hydrophilic groups, cationic hydrophilic groups and hydroxyl groups, and at least one functional group with a polymerizable carbon-carbon double bond (wherein the number of the functional groups with a polymerizable carbon-carbon double bond is one when the hydrophilic group is a hydroxyl-containing group); a compound (II) having two or more functional groups with a polymerizable carbon-carbon double bond (wherein the compound may have a hydroxyl group but is free from anionic hydrophilic groups and cationic hydrophilic groups); and at least one compound selected from a surfactant (III) having a hydrophilic moiety including an anionic hydrophilic group, a cationic hydrophilic group or two or more hydroxyl groups, and a hydrophobic moiety including an organic residue, and a compound (IV) having a siloxane bond and a molecular weight of 200 to 1,000,000 (wherein the surfactant (III) and the compound (IV) have no polymerizable carbon-carbon double bonds). The monolayer film has a gradient of hydrophilic group concentration (Sa/Da) of not less than 1.1 wherein Sa is the surface concentration of at least one type of hydrophilic groups selected from anionic hydrophilic groups, cationic hydrophilic groups and hydroxyl groups, and Da is the deep concentration of the hydrophilic groups at 1/2 of the thickness of the monolayer film.

  The present invention relates to processes for preparing a stable suspension of carbon nanoparticles in a thermal transfer fluid to enhance thermal conductive properties, viscosity, and lubricity. One process is to disperse carbon nanoparticles directly into a thermal transfer fluid and other additives in the present of surfactants with intermittent ultrasonication. The second process is carried out in three stages. First, carbon nanoparticles are dispersed into a volatile solvent. Then, a thermal transfer fluid, surfactants, and other additives are added into this intermediate dispersion and mixed thoroughly. At last, the volatile solvent is removed to produce a uniformly dispersed nanofluid. The third process is to disperse carbon nanoparticles at an elevated temperature into a homogeneous mixture of surfactants and other additives in a thermal transfer fluid with help of a physical agitation. The present invention also relates to compositions of carbon nanoparticle nanofluids, such as nanolubricants and nanogreases. The nanofluid of the present invention is a dispersion of carbon nanoparticles, particularly carbon nanotubes, in a thermal transfer fluid in the present of surfactants. Addition of surfactants significantly increases the stability of nanoparticle dispersion. For nanogreases, carbon nanoparticles function both as a thickener to modulate viscosity and as a solid heat transfer medium to enhance thermal conductivity and high temperature resistance.
