Abstract
In this paper, the morphology of nanocomposite polyester resins has been studied. The basis was polyester resin NH6586 produced by Kinte. Aluminum oxide nanofibers were introduced into the resin, which are single crystals or chains of single crystals with the γ- Al2O3 structure with a diameter of 5 to 15 nm and up to 1 mm in length. The additive was introduced into the resin by the industry standard twin screw extrusion method. At the same time, the influence on the uniformity of distribution of the addition of mineral filler - submicron particles of titanium dioxide - was studied. It has been shown that conventional methods of mixing the additive do not allow the nanofibers to be completely distributed. In such cases, they are distributed in the form of microbundles. The addition of mineralfiller to the polyester resin improves the distribution of the alumina nanofibers so that no bundle inclusions are observed in the resin cleavage. Thus, it can be concluded that mineral additives of isometric particles are an effective homogenizer of aluminum oxide nanofibers in polymeric materials.
