Introduction to Polymers

Polymers are complex molecules that are composed of many smaller repeating units. They are found in nature, manufactured by humans or created artificially in the laboratory. Polymers have a wide range of properties and uses, making them essential materials in everyday life. They are found in the form of solid and liquid materials, as well as gas, and they provide a range of unique benefits in terms of mechanical strength, electrical conductivity and thermal stability. Polymers can be used in everything from clothing to electronics and from medical devices to aerospace engineering.

What are the structural features of polymers?

The basic structural unit of polymers is a monomer. A monomer is a type of molecule that can be bound together to form larger molecules. Monomers are typically composed of hydrocarbons and their derivatives and can vary in size, structure and properties. When these monomers are joined together by covalent bonds, they form polymers. The basic structure of a polymer is usually the same. It consists of a backbone with repeating units of similar atomic structure, allowing the molecules to form a chain.

What are the different types of polymers?

Polymers can be divided into two main categories: natural polymers and synthetic polymers. Natural polymers are biopolymers molecules that are found in nature, such as proteins, cellulose, starch and DNA. Synthetic polymers are those which have been created or manufactured by humans. These polymers are further divided into thermoplastics, thermosets, elastomers and biodegradable polymers. Each type of polymer has unique properties and is used in a variety of applications.

Conclusion

Polymers are fundamental materials that play a crucial role in many sectors such as packaging, construction, aerospace and medical. Their wide range of properties and uses make them a sought-after material for a variety of industries. Polymer molecules consist of small repeating monomer units held together by covalent bonds to form larger molecules. The two main categories of polymers are natural polymers and synthetic polymers. Natural polymers are found in nature and synthetic polymers are created or manufactured by humans. Both types of polymers are used for a myriad of applications that continue to grow – demonstrating the importance of this material in our lives today.
