How are smart polymers used in light sensitive plasters?
Smart polymers in light-sensitive plasters can change their properties in response to light exposure. These polymers can be used in wound dressings or plasters that change color when exposed to UV light, indicating when the dressing needs to be changed. This allows for better monitoring of wounds and can help in preventing infection.
What are photo conductive polymers?
photoconductive polymers are materials that change their electrical conductivity when subject to light (infra red- visible - ultraviolet - gamma). They are mainly used in photocopiers and holography.
Examples of smart polymers?
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.
What property of sliver bromide makes it useful in photography?
Silver bromide is light-sensitive, meaning it reacts to light by forming silver particles, which creates an image. This property allows it to be used in photography for capturing and developing photos.
How are alkenes used to make polymers?
Alkenes are used to make polymers through a process called polymerization, where the double bond in the alkene is used to form the backbone of the polymer chain. By initiating polymerization reactions with catalysts, heat, or light, alkenes can be linked together to form long chains of repeating units, creating various types of synthetic polymers. Examples include polyethylene, polypropylene, and polystyrene.

What are light sensitive plasters?
It is used to stop you being hurt when you remove the plaster.
What and how do light sensitive polymers work?
They are used in hospitals as stitches because they will desolve in light and there is no need for them to be taken out.
Why can smart polymers be used for plasters on wounds?
Hydro gelplasters are used on wounds becausetheyreact to the state of the wound by either hydrating it or drying it. Wounds which have a lot of discharge or pus coming out of them are the ones they are usually used for as thehydro-gel absorbs this and lets the wound heal.
What is the basic job of plasters for wounds?
Plasters were used before band-aids were developed.
What Smart Textiles do you get?
Gore-tex - used for all-weather jackets and shoes , properties - breathable , lightweight and waterproofHeat sensitive - fire fighters clothing , can be used for decoration also for woundsKevlar- bullet proof material used for bullet proof vestsSilver technology - can be used in plasters !these are all smart materials :)
What is light sensitive paper and how does it work?
Light sensitive paper is a type of photographic paper that changes color when exposed to light. It contains light-sensitive chemicals that react to light by darkening in areas exposed to light, creating a visible image. This process is used in traditional darkroom photography to create prints from film negatives.
What are photo conductive polymers?

Why are your eyes so sensitive to sunlight?
Eyes can be sensitive to light due to medications that may be used. If a person has light eyes, they may have photophobia which is also a sensitivity to light of the sun. If you are sensitive to sunlight, then wearing a pair of sunglasses may help.
How can polymers be used in optical materials?
Polymers can be used in optical materials due to their transparency, light weight, and ease of processing. They can be used to make lenses, prisms, and other optical components. Polymers can also be engineered to have specific optical properties like refractive index and dispersion.
