Polyurethane nanocomposites filled up with boehmite modified by triethylphosphate are the new class of materials. Introduction of organic substituent leads to desintegration of boehmite molecues and results in obtaining nano-filler. Addition of the compatible substituent allows homogenic distribution of nano-filler in polymer matrix and improves properties of origin polymer.
In this study, effect of boehmite and its modification products on structure and properties of polyurethane were investigated. Tensile strenght, Young modulus, grindability and structure analysis of prepared composities were studied. Structure analysis was made by Atomic Force Microscopy. Nanofillers grain dimension analysis was conducted in Transmission Electron Microscopy.
