Das Hydrogel und das krystallinische Hydrat des Kupferoxyds

Abstract: Mit zwci Fjgnren iiii Text. SIWIN(; nnd LUCION haben neuerdings einige sehr wichtige Beobachtungen veroffentliclit iiber die Entwiisserung des blaueii gallertartigen Kupferoxyds (durch ein Alkali aus einer Losung von CuSO, gefallt) unter dem Einflusse verdunnter Salzlijsungen. Sie rnachen dabei keine Alitteilung iiher eiiien Unterscliied ewischen dem kolloidalen und dem krystallinischen Hydrat und legen also lreinen Nachtlrucik darauf, dafs sie iiiit einer Snbstanz iin kolloidalen Zustande x u tliua hatten, tl… Show more

“…Hydrogels were first discovered in 1894 [ 1 ] as a cross-linked polymer that swells in water [ 2 ]. The pH and temperature-sensitive phase transition effect of poly N-iso-propylacrylamide hydrogel were observed due to the hydrophobic bond formation [ 3 ].…”

“…the formation of fine particles using colloidal suspension followed by removal of solvent through evaporation. For the first time, appearance of hydrogel term in literature was noticed in 1894 and was utilized to give description about colloidal gel [2]. DuPont scientists in 1936 reported the synthesis of poly (2-hydroxyethyl methacrylate) (PHEMA) hydrogel [3].…”

“…Discovery of the colloidal state by GRAHAM (18) was followed by extensive studies by VAN BEMMELN (66,67,68,69) and ZSIGMONDY (73,74). Thermodynamic studies by KATZ (36) indicated significant changes in free energy and heat content in colloidal systemis at low water content.…”
