Characterization of Hydrogels with Amphiphilic Structures

abstract

English

Nowadays there is an increasing demand for hydrogels with modifiable properties, which would find application especially in health care, pharmacy, or common consumer industry. Inspiration for hydrogel structures can be found in extracellular matrix, which has the character of a hydrocolloid and which is often simulated by hydrogels. It also has a relatively complex composition and some components „only“ regulate biochemical processes, while others co‑create or influence its properties. Understanding the physicochemical properties of the extracellular matrix is very complex and yet not well described. Hydrogels in this work are trying to use the knowledge gained from the proper functioning of a living organism and then transfer it to the developed hydrogels. This work deals with the study of preparation and properties, especially rheology, of hydrogels, whose internal structure is modified and controlled by addition of suitable amphiphiles. the specific material solution of this work is based on simple hydrogel matrices, which were prepared from agarose and gelatin. In the frame of this contribution the formation of internal structures was caused by the addition of lecithin. the addition of amphiphilic substance affects the viscoelastic moduli, the values at the cross over point as well as the relaxation properties.
