General description

2-Hydroxyethyl cellulose (HEC) is a water soluble biopolymer that is majorly used as a thickener and an adhesive. It has water retention which also includes good film forming ability for protective covering.
Non-ionic water soluble polymer. Aqueous solutions are pseudoplastic. Readily disperses without lumping.

Application

Thickener, protective colloid, binder, stabilizer and suspending agent.

Microporous anodic aluminum oxide (AAO) membranes were modified by 3-glycidoxypropyltrimethoxysilane to produce terminal epoxy groups. These were used to covalently link hydroxyethyl celluloses (HEC) to amplify reactive groups of AAO membrane. The hydroxyl groups of HEC-AAO composite membrane were further
