Abstract:
Micro-nano materials, products obtained by covalently modifying the surfaces of micro/nano materials with hydrophilic materials, and methods for making the same. The micro/nano materials on the surfaces have carboxyl groups or/and pro-carboxyl groups which are converted into their active esters. The products are covalently modified by forming amide bonds between the active esters on the surfaces and the modification agents; where the modification agents are hydrophilic compounds and/or hydrophilic polymers bearing primary and/or secondary aliphatic amines. Monomers bearing carboxyl groups and/or pro-carboxyl groups are used to produce an adequate number of carboxyl groups and/or pro-carboxyl groups on the surface of a polymer material to be modified. The carboxyl groups and/or pro-carboxyl groups are converted into active esters. A reasonably-sized modification agent bearing primary and/or secondary amines, zwitterions and hydrophilic linear spacer arms is used to form amide bonds and obtain a covalently modified surface layer.

Claim (Index 3):
The method of  claim 2 , wherein the micro/nano material to be modified comprises an organic polymer, an organic polymer-inorganic micro/nanoparticle composite, and an organic polymer-organic micro/nanoparticle composite; micro/nanoparticles in making composite micro/nano material comprise one of magnetic nanoparticles, quantum dots, up-conversion luminescent particles, organic polymer particles and organic-inorganic composite particles, or a mixture thereof;\n in the polymerization reaction for making the micro/nano material, specific organic monomers in a covalent structure containing both a functional group for polymerization and a functional group selected from one or more of a carboxyl group, a pro-carboxyl group, an active ester, a cation, an anion, a neutral hydrophilic group, a metal ion chelating group and a protein-disulfide-selective modification group; and a ratio of the specific organic monomers to the total molar amount of monomers is 1% or more; when making the micro/nano material particles, a water-in-oil or oil-in-water microemulsion system is used to disperse the monomers into microemulsion for polymerization, or large-sized particles/films of polymer materials are mechanically broken to obtain the micro/nano material particles; and when the microemulsion system is used to disperse the monomers followed by polymerization, the specific organic monomers are suitable for single use or mixed use in any ratio as long as their solubility in the polymerization reaction phase satisfies the requirements.
