  • TERAHERTZ SPECTROSCOPY SYSTEM
    Publication number: 20250076192
    Abstract: The present application discloses a measurement unit for holding a sample (including a powder sample in small quantity, a scattered powder sample or an aqueous solution sample) for a terahertz beam irradiation; and a terahertz spectroscopy system with the measurement unit for measuring an absorption signal from the sample. In particular, the terahertz beam can be reflected for multiple times through the sample in the measurement unit for enhancing the absorption signal. The present application discloses three non-destructive e methods of measuring the absorption signal of the sample using the terahertz. spectroscopy system.

  • METHOD OF PREPARING FIBER-REINFORCED POLYMER COMPOSITES AND FIBER-REINFORCED POLYMER COMPOSITES PREPARED THEREOF
    Publication number: 20180155540
    Abstract: A method of preparing a fiber-reinforced polymer composite is provided. The method includes (a) providing a swollen clay material; (b) chemically modifying a surface of the swollen clay material with an organosilane to form a silane-modified clay material; (c) intercalating the silane-modified clay material with a binder to form an intercalated clay material; and (d) melt compounding the intercalated clay material with a mixture comprising a polymer and fiber to form the fiber-reinforced polymer composite. A fiber-reinforced polymer composite is also provided.
