The first level: use the following alumina forming agent to produce alumina, the alumina forming agent contains the partial hydrolysate of the alkyl aluminum compound containing trialkyl aluminum or a mixture thereof (in contrast to the alkyl aluminum compound Aluminium and a molar ratio of water in the range of 0.5 to 1.4 are hydrolyzed) and a solvent (a mixture of non-polar solvents or non-polar solvents). Alumina film and alumina particles can also be produced on or in substrates that are not resistant to polar solvents. The second level: A method for producing polyolefin-based polymer nanocomposite, the polyolefin-based polymer nanocomposite contains zinc oxide particles or alumina particles, and the production method uses a solution containing alkyl zinc partial hydrolysate , Or a solution containing partial hydrolysate of aluminum alkyl. A polyolefin-based polymer nanocomposite, which contains a polyolefin substrate and zinc oxide particles or aluminum oxide particles, does not contain a dispersant, and the average particle size of the zinc oxide particles or aluminum oxide particles is less than 100 nm. |
