What are smart polymers and write their applications?
Smart polymers, also known as stimuli-responsive polymers or intelligent materials, appear in highly specialized items, and everyday things. Their uses include sensors and actuators like artificial muscles; production of hydrogels; biodegradable packaging; and in biomedical engineering.
What are synthetic polymers used for?
Uses Of Synthetic Polymers The polymer called Polyethylene is used in plastic bags and film wraps. Polyvinyl Chloride(PVC) is used in siding, pipes, flooring purposes. The synthetic polymer Polystyrene is used in cabinets and in packaging. Polyvinyl acetate is used in adhesives and latex paints.
Where are photochromic materials used?
Photochromic materials can be used for the design of optical switches, optical data storage devices, energy-conserving coatings, eye-protection glasses, and privacy shields. Photochromic materials and systems have several important uses depending on the rates of the optical transformations.
Does Lenskart provide photochromic lenses?
Are Photochromic Lenses The Right Choice for You – Spectacular by Lenskart.
How is polymer chemistry used in everyday life?
Product made from polymers are all around us: clothing made from synthetic fibers, polyethylene cups, fiberglass, nylon bearings, plastic bags, polymer-based paints, epoxy glue, polyurethane foam cushion, silicone heart valves, and Teflon-coated cookware. Polymers are obtained through chemical reaction of monomers.
Are hydrogels smart polymers?
Light-responsive smart hydrogels are composed of a polymeric network possessing light reactive groups such as photochromic moieties. Upon light irradiation, these hydrogels change their physical and/or chemical properties including elasticity, viscosity, shape and swelling degree.
Where are synthetic polymers used?
Synthetic Polymers in Everyday Use Some familiar household synthetic polymers include nylons in textiles and fabrics, Teflon in non-stick pans, and polyvinyl chloride in pipes. The common PET bottles are made of a synthetic polymer, polyethylene terephthalate.
What are the examples of synthetic polymers?
Synthetic polymers are derived from petroleum oil, and made by scientists and engineers. Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. Natural polymers occur in nature and can be extracted. They are often water-based.
What are the applications of photochromic materials?
Photochromics are the most attractive and promising materials for a vast number of applications in many different fields. Some of the best known applications for photochromic materials are: in ophthalmics, especially in lenses for sunglasses, cosmetics, actinometrical, and heat measurements, optical memories for data storage,…
What is the service life of photochromic polymers?
Unfortunately, due to the degradation of photochromic compounds [32], their service life under sunlight does not exceed 3 years [31]. Apparently, for this reason, photochromic polymeric materials have not yet been created for glazing of buildings and vehicles of various types.
What are Photochromic Ophthalmic polymer lenses made of?
Nevertheless, at present, various companies have created a range of photochromic ophthalmic polymer lenses based on organic photochromic compounds using the most photodegradation-resistant spirooxazines ( Scheme 7.3) and chromenes ( Scheme 7.4) [30]. Scheme 7.3. Scheme 7.4.
What is the difference between organic and inorganic photochromic materials?
Photochromic materials are generally unstable organic molecules, such as spirobenzopyrans, chromenes, fulgides, diarylethenes, whereas inorganic and biological photochromes have lower overall efficiency, compared to organic photochromic compounds.
