Self-assembled nano-structured particle and methods for preparing

A process for preparing a stable, colloidal dispersion of boron nitride nanoparticles, comprising:

• a. heating an acid medium in a reactor with mixing, wherein the acid medium is a 50% glyoxylic acid solution;
• b. adding a host vessel comprising β-cyclodextrin with mixing to the acid medium to form a gel;
• c. adding a solid guest particle that is hexagonal boron nitride to the gel with mixing to the gel to form a reaction mixture;
• d. stirring the reaction mixture at elevated temperatures over time to allow particle size reduction and annealing to occur;
• e. adding an additional acid that is superphosphoric acid 105% to the reaction mixture at least once during the particle size reduction and annealing stage, with mixing;
• f. adding glucosamine to the reaction mixture with mixing;
• g. optionally, adding maleic anhydride to the reaction mixture with mixing;
• and
• h. dry quenching the mixture with a dry basic compound,
• wherein the temperatures for the reaction range between 30° C. and 110° C. and are adjusted with the range to maintain mixing or the reaction mixture and to keep viscosity and tackiness of the reaction mixture elevated.
