Abstract: The present disclosure relates to a method for stably dispersing nanoparticles of a material in a curable polymer, the method comprising: a) providing a curable pre-polymer; b) providing particles of the material; and c) compounding the curable pre-polymer and the particles at a compounding temperature sufficiently high to obtain a curable melt mixture and sufficiently low for the curable melt mixture to develop a pre-determined viscosity upon compounding. The compounding is performed by applying a shear force to the heated curable melt mixture, whereby nanoparticles are formed from the particles, the viscosity of the melt being such that the nanoparticles remain dispersed in the mixture.

Abstract: A bone-regeneration material that contains calcium phosphate particles in a biodegradable fiber containing PLGA by using electrospinning. A PLGA resin is heated in a kneader to soften until the viscosity of the resin becomes 102 to 107 Pa·s. A powder of calcium phosphate fine particles is added and mixed with the softened PLGA resin, while the blade of the kneader rotates. The mixture is kneaded by applying thermal and mechanical energy to the mixture through the continuous rotation of the blade of the kneader in the heated state, and aggregations of the calcium phosphate fine particles are disintegrated to prepare a composite in which the calcium phosphate fine particles are dispersed in the PLGA resin. The composite is dissolved in a solvent to prepare a spinning solution. Electrospinning is performed on the spinning solution to manufacture biodegradable fibers having therein the calcium phosphate fine particles substantially uniformly dispersed.

Abstract: A method for producing aluminum oxide is provided. The method uses an aluminum-oxide-forming agent containing a partially hydrolyzed aluminum alkyl compound containing an aluminum trialkyl or a mixture thereof, and a solvent. It is thus possible to produce an aluminum oxide thin film or aluminum oxide particles on or in a substrate that is not resistant to polar solvents. A method of producing a polyolefin-based polymer nanocomposite containing zinc oxide particles or aluminum oxide particles using a solution containing a partially hydrolyzed zinc alkyl or a solution containing a partially hydrolyzed aluminum alkyl is also provided. The polyolefin-based polymer nanocomposite contains a polyolefin substrate and zinc oxide particles or aluminum oxide particles, and does not contain a dispersant. The zinc oxide particles or aluminum oxide particles have an average particle size of less than 100 nm.
