A range of natural and synthetic polymers are used to design nanocomposite network. By controlling the interactions between nanoparticles and polymer chains, a range of physical, chemical and biological properties can be engineered. The combination of organic (polymer) and inorganic (clay) structure gives these hydrogels improved physical, chemical, electrical, biological, and swelling/de-swelling properties that can not be achieved by either material alone. Inspired by flexible biological tissues, researchers incorporate carbon-based, polymeric, ceramic and/or metallic nanomaterials to give these hydrogels superior characteristics like optical properties and stimulus-sensitivity which can potentially be very helpful to medical (especially drug delivery and stem cell engineering) and mechanical fields. == Synthesis == The synthesis of nanocomposite hydrogels is a process that requires specific material and method. These polymers need to be made up of equally spaced out, 30mm in diameter, clay platelets that can swell and exfoliate in the presence of water. The clay platelets act as crosslinks to create modified functionality that enables the hydrogels to have superior elasticity and toughness that resembles closely to that of biological tissue. Using clay platelets that do not swell or exfoliate in water, using an organic crosslinker such as N,N-methylenebisacrylamide(BIS), mixing of clay and BIS, or preparing nanocomposite hydrogels in a method other than crosslink will not be successful. Despite all the specifications, the process of synthesizing nanocomposite hydrogels is simple and because of the flexible nature of the material, these hydrogels can be easily made to come in different shapes such as huge blocks, sheets, thin films, rods, hollow tubes, spheres, bellows and uneven sheets. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nanocomposite hydrogels」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
