What is polymer viscoelasticity?
What is polymer viscoelasticity?
Specifically, viscoelasticity is a molecular rearrangement. When a stress is applied to a viscoelastic material such as a polymer, parts of the long polymer chain change positions. This movement or rearrangement is called creep.
Is polymer a science engineer?
Polymer science or macromolecular science is a subfield of materials science concerned with polymers, primarily synthetic polymers such as plastics and elastomers. The field of polymer science includes researchers in multiple disciplines including chemistry, physics, and engineering.
What does Polymer Engineering do?
A polymer engineer primarily works in plastics development. In this career, you develop and test plastics or related materials. Your responsibilities include the fabrication of new polymers, working with the prototype, and designing new equipment to process these materials.
What causes viscoelasticity in polymers?
Viscoelasticity is caused by temporary connections between fiber-like particles. Polymers always show a viscoelastic behavior because they consist of long molecules able to make temporary connections with their neighbors.
Why is polymer elastic?
The long polymer chains cross-link during curing, i.e., vulcanizing. The elasticity is derived from the ability of the long chains to reconfigure themselves to distribute an applied stress. The covalent cross-linkages ensure that the elastomer will return to its original configuration when the stress is removed.
Is polymer Engineering good?
Due to the importance of the field in our daily lives, the requirement for Polymer Engineers is rising at a very fast pace. Polymer Engineers with enhanced knowledge is finding good positions in the industries viz. Petroleum Industry, Oil Industry, Polymer Industry, Rubber Industry etc.
Why is polymer science important?
What are Bio-Polymers? Bio-polymers are the basis of all life on our planet. Polypeptides (proteins) and polynucleotides (DNA and RNA) dominate the functional and informational machinery of life, while polysaccharides (sugars) are important in physical structure, energy storage, and intermolecular interactions.
