    摘要： Disclosed a preparation method of a green, biodegradable, and multifunctional collagen-based nanocomposite film, and overcomes the problems of difficult biodegradation, poor barrier property, and single function of food packaging materials in the existing technologies. The present invention includes the following steps: adding silicate nanosheet into deionized water for ultrasonic dispersion; then adding polyphenolic acid into the mixture, wherein a mass ratio of the polyphenolic acid to the silicate nanosheet is 1:(0.2˜1); and adjusting the pH value to 3.0˜4.0 to obtain a solution A; adding collagen with a concentration of 5 g/L into an acetic acid solution, and fully dissolving the collagen to obtain a solution B; isovolumetrically mixing the solution A with the solution B, stirring at room temperature, and adjusting the pH value to 4.5˜5.5 to obtain a casting solution; and pouring the casting solution into a polytetrafluoroethylene mold, and naturally drying to obtain a nanocomposite film.

    摘要： Preparing a demulsifier, an oil soluble imidazoline corrosion inhibitor, an alkylphenolic resin, an alkylphenolic resin oxyalkylate, a paraffin inhibitor, a defoamer, an oil soluble scavenger, an oil soluble cleaner, a wetting agent, a surfactant, a foamer, and combinations thereof, in a non-limiting embodiment, in the absence of a BTEX solvent would be more beneficial to the environment than the same products prepared with BTEX solvent(s). The method may include adding an organic solvent to a mixture to form the aforementioned material(s). The organic solvent may be or include propylene glycol methyl ether acetate (PGMEA currently marketed as DOWANOL PMA™), dipropylene glycol methyl ether acetate (currently marketed as DOWANOL DPMA™), diisobutyl ketone (DIBK), methyl isobutylketone (MIBK), and mixtures thereof.

    摘要： The present invention discloses a polymeric polyamine which can be produced by polymerizing polyoxyalkylene-amine and a linker. The linker can be anhydride, carboxylic acid, epoxy, isocyanate or poly(styrene-co-maleic anhydride) copolymers (SMA). The present invention also discloses a method for stabilizing the Ag nanoparticles with polymeric polyamine. The polymeric polyamine serving as a stabilizer or dispersant is mixed with a water solution of silver salt and then a reducer is provided to reduce the silver ions and form an organic or a water solution of Ag nanoparticles. Water or solvent of this solution can be further removed through a heating, freezing or decompression process, and thus solid content of the solution can be increased. The concentrated solution also can be diluted to obtain a stable dispersion without aggregation.

    摘要： A molding compound is provided for use in encapsulating electronic packages which include an optoelectronic component, such as an LED. The molding compound includes a partially cured epoxy composition, an antioxidant, and, optionally, a phosphor material substantially uniformly distributed throughout the epoxy composition. The optional phosphor material may be suspended within the epoxy composition by pre-reacting a portion of the epoxy composition prior to B-staging of the molding compound. As such, the optional phosphor material is suspended within the epoxy composition, thereby preventing settling of the phosphor material during B-staging, as well as during curing of the molding compound in the encapsulation process.
