Phase-change suspension fluid composition including polyethylene oxide particles and method for manufacturing the same

A suspension fluid prepared by dispersing polyethylene oxide particles into a solvent including water and one or more types of compounds selected from the group consisting of ethylene glycol and propylene glycol, and a method for manufacturing the same. The phase-change suspension fluid can be a shear-thinning fluid showing a constant newtonian behavior in a low shear rate or low frequency region, but showing a non-newtonian behavior appearing as liquid-like suspension in a high shear rate or high frequency region due to viscosity decrease, and is capable of reversible phase changes by the vibration of a vehicle, and therefore, may provide effects of having advantages of a hydraulic bush in a low frequency region and also having advantages of a solid bush in a high frequency region.

PRECISE SIZE AND SHAPE CONTROL OF COLLOIDS USING TEMPERATURE-ACTIVE BLOCK-COPOLYMER MICELLES

The present disclosure describes methods of producing colloids of precise sizes and shapes using temperature responsive block copolymers. A method of precise size control of colloids may include producing colloids in a solution of block copolymers, and POSS colloids. The temperature of the solution may be increased at a set rate to swell mesoscopic droplets to a precise size. A method of precise shape control of colloids may include polymerizing colloids in a solution of block copolymers, and POSS colloids and manipulating the temperature of the solution. In particular, the temperature of the solution may be increased at a set rate to swell and polymerize mesoscopic droplets and subsequently decreased at a set rate to collapse the colloids into a precise shape.
