Hydorges Flashcards
1
Q
Hydrogels
A
Is a 3-D network of hydrophilic polymers that can swell in water and hold a large volume of water while maintaining the structure
2
Q
What are many hydrogels are polymers of?
A
Carbonylic acids
3
Q
What happens when polymers are put into water?
A
When the polymers are put into water, the hydrogen atom react and come off as positive ions
4
Q
What does that leave then
A
Negative ions along the length of polymer chain
5
Q
A
The hydrogen and water molecule is attracted to the negative carbolic ion as water is a polar molecule and this slightly positively charged. This allows hydrogen bonding to occur between the hydrogen water.
