NANO-PARTICLES HAVING AMPHOTERIC PROPERTY, A SYNTHESIS OF MOLECULAR SIEVE HAVING AMPHOTERIC ION FOR NANO-PARTICLE SURFACE MODIFICATION AND APPLICATIONS THEREOF CAPABLE OF MANUFACTURING STABLE NANO-PARTICLES IN WIDE RANGE OF PH AND SALT CONCENTRATION

摘要

PURPOSE: A nano-particle having amphoteric property, a synthesis of molecular sieve having amphoteric ion for nano-particle surface modification and applications thereof are provided to improve surface dispersibility of the nano-particles by forming amphoteric ion molecules.;CONSTITUTION: A nano-particle has negative ion and cation on the surface at the same time. Amphoteric ion molecular sieve is formed on surface of the nano-particle. The nano-particle is electrically neutral. The nano-particle is an arbitrary particle having nano unit with a diameter of less than 1000 nano meters. The nano-particle is 0.5-10 micron. The molecular sieve is monomer, oligomer, or polymer phosphorus compound. A surface modification of the nano particle comprises a step of reacting the nano-particle with amphoteric ion molecular sieve in order to manufacture a nano-particle having negative ion and cation at the same time.;COPYRIGHT KIPO 2012
