Transparent zeolite-polymer hybrid material with tunable properties

摘要

The invention is about the preparation of novel highly transparent zeolite-doped polymer and zeolites monolayers. External coating of the zeolite crystals by covalently linked functionalized alkoxysilane derivatives allows for an efficient dispersion of the nano zeolite particles into an organic liquid monomer; the following co-polymerisation process leads to a hard, insoluble and transparent material containing said zeolites. Optical properties such as colour, refractive index, Abbe number or photochromism can be fine tuned by simply changing zeolite loading, while transparency is maintained.
