A mono-disperse hollow particle is stably provided by excellent coacervate forming capability, such that it is expected to be beneficially used as a carrier in various fields such as a cosmetic, a paint, plastic, rubber, a synthetic wood, a refractory material, and an agricultural chemical.

Particulate material comprising rough mesoporous hollow nanoparticles. The rough mesoporous hollow nanoparticles may comprise a mesoporous shell, the external surface of which has projections thereon, the projections having smaller sizes than the particle size. The particulate material may be used to deliver active agents, such as insecticides and pesticides. The active agents can enter into the hollow core of the particles and be protected from degradation by sunlight. The rough surface of the particles retains the particles on plant leaves or animal hair. Methods for forming the particles are also described. Carbon particles and methods for forming carbon particles are also described.

The invention relates to the field of capsules having a high load of active ingredients or substances, to the use thereof in cosmetic preparations, pharmaceuticals, household products, cleaning agents and technical compositions, e.g. adhesive and coating compositions, and to the manufacturing of the capsules.

The present invention relates to a fire extinguishing micro-capsule, a method for manufacturing the same, and a fire extinguisher using the same. The fire extinguishing micro-capsule has a core-shell structure in which a core includes a liquid fire extinguishing agent and a shell uses a high-density non-porous polymer material. A decapsulation process of the fire extinguishing micro-capsule occurs in a narrow time and temperature range at a rate of at least 150%/min, and the stability of the agent in water and other solvents is significantly increased. A fire extinguisher including the fire extinguishing micro-capsule has increased lifetime and operational efficiency.

A method for controlling the encapsulation efficiency and burst release of water soluble molecules from nanoparticle and microparticle formulations produced by the inverted Flash NanoPrecipitation (iFNP) process and subsequent processing steps is presented. The processing steps and materials used can be adjusted to tune the encapsulation efficiency and burst release of the encapsulated water-soluble material. The encapsulation efficiency of the soluble agent in the particles and the burst release of the soluble agent from the particles can be controlled by: (1) the copolymers used in the assembly or coating process, (2) the degree of crosslinking of the nanoparticle core, (3) the incorporation of small molecule or polymeric additives, and/or (4) the processing and release conditions employed.

A phase change microcapsule having high blending fluidity and high latent heat of phase change, and a preparation method thereof is provided. The preparation method of the phase change microcapsules includes following steps of 1) heating and melting an organic phase change material to obtain a liquid core material; 2) evenly dispersing an emulsifying and dispersing agent in water, then adding carbamide, ammonium chloride and polyphenol, and mixing them evenly, followed by adjusting a pH value to 2.5-3.5 to obtain an aqueous phase solution; 3) adding the liquid core material and a defoaming agent to the aqueous phase solution to perform an emulsification to obtain an oil-in-water emulsion; and 4) adding a formaldehyde solution and a dispersing agent to the oil-in-water emulsion, after reaction is completed, performing a filtration, washing and drying.
