The present invention relates to a self-assembly preparation method of a nanocomposite material, and more particularly, relates to a self-assembly preparation method of a nanocomposite material comprising steps of: spraying a drug-containing solution onto metal aerosol nanoparticles to form a drug layer on the metal aerosol nanoparticles; and spraying a polymer-containing solution onto the metal aerosol nanoparticles, on which the drug layer is formed, to form a polymer layer on the drug layer, whereby since the method involves no liquid chemical process upon producing the metal aerosol nanoparticles, the processes are simple and can be performed even at a low temperature to suppress deformation of an organic or a drug, and the release rate of the drug, or the like can be easily controlled through metal types of metal aerosol nanoparticles, modification, and the like.

The present disclosure provides methods for functionalizing the surfaces of cellulose nanoparticles. In embodiments, nanoparticles are aerosolized, and then passed through a flow reactor where they are contacted with gaseous reactants to functionalize the surface of the nanoparticles. In other embodiments, the nanoparticles are aerosolized, and then passed through a plasma reactor where they are contacted with gaseous reactants to functionalize the surface of the nanoparticles. Once the functionalized nanoparticles are produced, they may be combined with polymers to form polymer composites having both a polymer and the functionalized nanoparticles. Systems for producing these functionalized nanoparticles, coupled with downstream polymer processing equipment for forming the polymer composites, are also provided.

The present application provides aerosol processes for selectively incorporating properties of solid precursor particles into processed materials is provided. In one aspect, a carrier gas and a precursor mixture are injected into an aerosol generator. The precursor mixture includes solid precursor particles and a liquid component. One or more ultrasonic transducers are applied to the to the precursor mixture in the aerosol generator to aerosolize a portion of the precursor mixture that comprises solid particles that are smaller than a predetermined size. The aerosolized portion of the precursor mixture is transferred, via the carrier gas, into a reactor. The aerosolized portion in the reactor is then dried and sometimes reacted to produce solid product particles, and the solid product particles are collected in a particle collector.

A system for producing dry nanoparticles from a liquid includes a closed tubing system which incorporates a mister, heater and an electrostatic collector therein. The system is able to produce dry nanoparticles from liquid-suspensions and from solvent solutions.

A controlled-volume spray deposition system has a fluid feed system including a pair of bi-directional, counter-rotating rollers to dispense fluid as a first surface, the rollers operable to rotate in a first direction to dispense the fluid, a second surface positioned to receive the fluid when the rollers rotate in the first direction, and the rollers operable to rotate in a second direction to retract the fluid to cause the fluid to stretch and form a filament until it breaks to form a spray. A method of generating a controlled-volume spray includes feeding fluid between two counter-rotating rollers as a first surface as they rotate in a first direction until the fluid contacts a second surface, reversing the counter-rotating rollers such that they pull the fluid to form a fluid filament, and causing the filament to break into a spray.
