It demonstrates solvent vapour annealing to improve the long-range order of the templates, and investigates the unique crystallisation behaviour of their semicrystalline block. Furthermore, it shows that gyroid optical metamaterials that exhibit only short-range order are optically equivalent to nanoporous gold, and that the anomalous linear dichroism of gyroid optical metamaterials with long-range order is the result of the surface termination of the bulk gyroid morphology. \u003c\/p\u003e\n\nOptical metamaterials are artificially engineered materials that, by virtue of their structure rather than their chemistry, may exhibit various optical properties not otherwise encountered in nature (e.g. a negative refractive index). However, these structures must be significantly smaller than the wavelength of visible light and are therefore challenging to fabricate using traditional “top down” techniques. Instead, a “bottom up” approach can be used, whereby optical metamaterials are fabricated via templates created by the self-assembly of block-copolymers. One such morphology is the gyroid, a chiral, continuous and triply periodic cubic network found in a range of natural and synthetic self-assembled systems.\u003cp\u003e\u003c\/p\u003e\n            \u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783030030100\"\u003e\u003ch3\u003eSolvent Vapour Annealing, Confined Crystallisation, and Optical Anisotropy\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Hardcover - 9783030030100","offer_id":32989961486429,"sku":"9783030030100","price":106.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/e1bc6ba8-c941-4b17-8414-622d3abcf850.jpg?v=1775277109","url":"https:\/\/shop.autorenwelt.de\/products\/gyroid-optical-metamaterials-solvent-vapour-annealing-confined-crystallisation-and-optical-anisotropy-von-james-a-dolan","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
