  • Injectable and shearing-thinning microbeads gel, use thereof, and method for preparing the same
    Patent number: 11311481
    Abstract: The present disclosure provides an injectable and shearing-thinning microbeads gel including a first microgel and a second microgel. The first microgel has a first electric charge and includes a plurality of first gel microspheres. The second microgel has a second electric charge and includes a plurality of second gel microspheres. The first electric charge is opposite to the second electric charge, the average particle size of the first gel microspheres is equal to the average particle size of the second gel microspheres, each of the first gel microspheres includes an acrylic chitosan polymer, an acrylic silk polymer, or a combination thereof, and each of the second gel microspheres includes an acrylic gelatin polymer, an acrylic hyaluronic acid polymer, an acrylic alginate polymer, or a combination thereof.
    Type: Grant

  • Method for collecting oil with modified clay
    Patent number: 8647513
    Abstract: The present invention provides a method for collecting oil with a modified clay. By mixing the modified clay and oil, the oil can be adsorbed to the clay. The modified clay is obtained by intercalating a hydrophobic polymer such as acidified poly(oxyalkylene)-amine into layered silicate clay, mica or talc to enlarge the interlayer space. The modified clay thus becomes hydrophobic and adsorption to the oil is promoted.
