how are smart polymers used in light sensitive plasters
Smart polymers can be used for heart valves and many other medical uses. In addition to this smart polymers are polymers (plastics) that can change in response to changes in the environment (i.e. temp, presence of water, pH, light etc.) Uses of smart polymers are: hydrogels (nappies and moisture crystals used in compost so your hanging baskets don't dry out!), plasters (band aids) that lose their stickiness when you want to take them off so dont rip your skin off, biodegradable plastic bags, non-stick chewing gum and even biological uses like detecting blood glucose levels and triggering the release of insulin.
polysaccharide
2CaSO4.H2O is known as Plaster of Paris.
Polybutane?
sterne
olestra
The chemical name for the polymer is polytetrafluoroethylene (PTFE).
A polymer is a large molecule made up of repeating units. These units are called monomers. In a polymer, monomers may be both identical or non identical. In polyamide, as the name suggests, the monomers are amides and it is a polymer.
hydrolysis
u study in standard 8, DPS, Kalinga. right?
first aid kit!
Galactan or glucose
