The main purpose of this study was to construct quasi-equilibrium phase diagrams of K15\/UV1 and K21\/UV1. Phase separation of liquid crystal\/pre-polymer system was observed using polarized optical microscopy. Liquid crystal\/Pre-polymer mixtures (K15\/UV1 and K21\/UV1 mixtures) were prepared with increasing percentage of liquid crystal in pre-polymer. Each sample was then subjected to quasi-equilibrium thermal cycles. Phase separation was detected by the onset of the formation of liquid crystal droplets in the homogeneous mixture. A quasi-equilibrium phase diagram of K15\/UV1 was constructed by plotting quasi-equilibrium phase separation temperature with respect to K15 percentage in UV1 pre-polymer. For K21\/UV1 mixtures, quasi-equilibrium thermal cycles resulted in crystallization. We decided to run slow-rate thermal cycles instead of quasi-equilibrium thermal cycles. Phase diagram of K21\/UV1 was constructed using the slow-rate thermal cycle data.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838350158\"\u003e\u003ch3\u003eStudies of Thermally Induced Phase Separation of Liquid Crystals and Pre-polymer Mixtures\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838350158","offer_id":39469158400093,"sku":"9783838350158","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/81c4b8df-8b9b-4bc4-aa3d-3025813e6d8a.jpg?v=1759038358","url":"https:\/\/shop.autorenwelt.de\/products\/liquid-crystal-and-its-quasi-equilibrium-phase-separation-von-mallika-dhar","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
