Description
General description
Hydroxypropyl cellulose (HPC) is a nonionic derivativeof cellulose. It is a thermosensitive, biodegradable polymer with low criticalsolution temperature.
Application
Hydroxypropyl cellulose can be used to prepare composite nanospheres for drug delivery systems. Hydroxypropyl methacrylate/hydroxy cellulose graft copolymers can be used as matrices for controlled-release tablets. It can also be used as an electrolyte additive to prepare gel polymerelectrolytes for dye-sensitized solar cells.
