摘要 |
A method for modifying an inorganic tubule, such as halloysite, cylindrite, boulangerite, or imogolite, with a functionalized block copolymer for improving compatibility with a thermoplastic or thermoset polymer matrix and a composition for the modified inorganic tubule and for the modified inorganic tubule-polymer matrix are provided. In one embodiment, the block copolymer can be added to a slurry of the inorganic tubules. The pH of the slurry can be manipulated to promote ionic bonding between the inorganic tubules and one block of the block copolymer. The other block of the block copolymer is selected for compatibility with the polymer matrix for a particular application.
