Examples of smart polymers

Answer 1

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.

Answer 2

Smart polymers are plastics which change or react in a certain way according to the environment they are in. Smart alloys can be affected by light, heat pressure, pH and water to name a few. Smart alloys are strong, tough, easy to colour and mould, and flexible.
Smart polymers are polymers (plastics) that specially change according to their environment and their surroundings. Some examples of environmental changes that affect polymers are temperature, the presence of water, pH, the presence/intensity of light, etc.

The main properties of smart polymers are that they are strong, flexible, easy to colour, easy to mould, and tough.

Some uses of smart polymers are: Nappies, Plasters, helmets, plastic bags, non-stick chewing gum, climbing ropes, plastic bottles and many more.

Answer 3

Shape memory polymers (SMPs) are polymeric smart materials that have the ability to return from a deformed state (temporary shape) to their original (permanent) shape induced by an external stimulus (trigger), such as temperature change.

Answer 4

First let's define what a polymer is. A polymer is just a large molecule with repeating sub-units. Polymers are very common. Plastics are polymers, but so are many important biological molecules. So, for example, PVC pipes are made of polyvinyl chloride. Vinyl chloride, an organic molecule, is the repeating sub-unit. Polystyrene is made from repeating sub-units of styrene, another organic moleucle. DNA is a biological polymer made of repeating sub-units of adenine, guanine, thymine, and uracil. Proteins are also biological polymers that are made of sub-units called amino acids. A smart polymer is not a polymer with a high IQ, it's a polymer that is able to adapt according to the environment that it is in. Smart polymers are also sometimes called stimuli responsive polymers. A smart polymer could be sensitive to temperature, pressure, pH, or any other environmental condition. PVC, which we already discussed as an example of a polymer, is not a smart polymer. A PVC pipe will not adapt to changing pressure, temperature, or anything else in its environment.
Smart polymers have found their greatest applications in biochemistry. They have been used in targeted drug delivery. The difficulty with targeted drug delivery is that our stomachs are incredibly harsh environments. This means that ingested pharmaceuticals can be broken down in the stomach before they even have the chance to do any good. A drug that is protected by a smart polymer can pass through the stomach and release into your body at a later time. This is just one use of smart polymers.

Answer 5

Ista and Lopez employed poly( N -isopropylacryl-amide)

Answer 6

Smart polymer is a polymer that changes its characteristic depending on what environment it is in. This factor can be tmeperature, PH, intensity of light or electric field.
