PREPARATION APPARATUS FOR NANOCOMPOSITE MATERIAL AND SELF-ASSEMBLY PREPARATION METHOD
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.
Methods and systems for creating aerosols
Aerosols can be created by filament stretching and breaking of Newtonian and non-Newtonian fluids by applying a strain to and stretching the fluid. The fluid is stretched along a strain pathway and forms a fluid filament between diverging surfaces. The stretched fluid filament breaks into droplets that can be harvested to form a mist or aerosol. The aerosol creation systems can include one or more pairs of counter-rotating rollers that are positioned adjacent to each other that stretch the fluid or a pair of pistons that move toward and away from each other to stretch the fluid. Some aerosol creation systems can include multiple pairs of counter-rotating rollers that are positioned in a circular, oval, or linear pattern. The aerosol creation system with multiple pairs of counter-rotating rollers can generate mist is one or more directions and can be positioned between two concentric rings or linearly, among other configurations.
METHODS AND SYSTEMS FOR CREATING AEROSOLS
A process of creating an aerosol includes coating at least one of a pair of counter-rotating, adjacent rollers with a fluid, the pair of counter-rotating rollers defining a nip therebetween, rotating the counter-rotating rollers to cause the fluid to be drawn into an upstream side of the nip, causing fluid filaments of the fluid to form on a downstream side of the nip, the fluid filaments stretching between respective surfaces of the pair of counter-rotating rollers and breaking into droplets on the downstream side of the nip, and harvesting the droplets at the downstream side of the nip.
