Traditional hydrogel dressings generally
have poor mechanical
properties
and stability when subjected to external stress due to the undesirable
chain entanglement structure of their single valence bond compositions.
Therefore, it is particularly important to develop a type of gel dressing
with good mechanical strength, stability, and environment-friendly
monitoring. In this work, a transparent, pH-sensitive, highly stretchable,
and biocompatible anthocyanidin ionogel dressing was prepared, realizing
green and accurate detection. Attributed to the antibacterial activity
of the ionic liquid, the biocompatibility of the pectin, and the ability
to scavenge free radicals of the anthocyanidin, the ionogel dressing
exhibited excellent re-epithelialization in the 14 day wound healing
process. Besides, changes in pH values monitoring of the ionogel over
3 days coincided with normal wound exudate. The obtained ionogel also
showed good water retention, swelling properties, mechanical stretchability,
and 5 week stability, illustrating great potential in wound dressings.
