Imagine losing half of your closet, and half of your collections.
It'd be half the world you're currently in, because many things in the world are made of polymers.
Crystalline polymers have a highly ordered molecular structure with repeating patterns, while amorphous polymers have a random molecular arrangement without distinct patterns. Crystalline polymers tend to be more rigid and have higher melting points, while amorphous polymers are more flexible and have lower melting points.
Amorphous polymers have randomly arranged molecular chains, making them flexible and transparent, while crystalline polymers have ordered molecular chains, making them rigid and opaque.
Melt spinning is used for polymers that can be melted i.e. the polymers must have a melting temperature (thermoplastic polymers). Dry spinning is used for polymers that do no have melting temperature and need to be dissolved in solvent (thermoset polymers). In case of melt spinning, the polymer solidifies by cooling after being extruded from the spinneret. Whereas, in case of dry spinning, the polymer solidifies through evaporation of solvents and this is achieved by a stream of air or inert gas.
Yes, polymers can be good insulators because they have high electrical resistivity compared to metals. This property makes them useful in applications where electrical conductivity needs to be minimized, such as in the insulation of electrical wires or in electronic components.
Nature Physics was created in 2005.
Nature polymers and synthetic polymers are both large molecules made up of repeating units called monomers. They both have high molecular weights and exhibit similar properties like flexibility, strength, and durability. Additionally, both nature and synthetic polymers can be engineered to have specific properties for various applications.
No, not all polymers are man-made. Some polymers can be found in nature, such as proteins, cellulose, and DNA. These natural polymers have unique properties and functions in living organisms.
There are several polymers in living beings, for example, proteins, DNA, RNA, and polysaccharides.
Examples: starch, cellulose, polypeptides, nucleic acids.
Composite materials can include polymers as one of their components. Polymers are often used as matrices or reinforcement materials in composites due to their versatility, lightweight nature, and strength. Examples of polymer-based composites include carbon fiber reinforced polymers (CFRP) and glass fiber reinforced polymers (GFRP).
Rubber is a natural polymers with elastic and plastic type behavior. It is found in nature and extracted from trees. PET (soda bottles) Polyethylene Terephthalate is a synthetic polymer and not found in nature.
1. Polyethylene.2. Polyester.These are the main two types of plastics;there may be many more plastics lying on the grounds of this big chunk of land[EARTH].
A natural polymer would be rubber which is obtained from nature. A synthetic polymer would be polybutadiene which behaves like rubber.
Natural polymers are discussed in other web pages and include:Proteins - silk, collagen, keratin.Carbohydrates - cellulose, starch, glycogenDNA - RNAOther Natural polymers: Rubber (hydrocarbon base) and silicones (alternating silicon and oxygen).
A polymer is formed when monomers are joined together through chemical bonds. Polymeric macromolecules can have a wide range of functions and properties depending on the specific monomer units and how they are linked. Examples of polymers in nature include proteins, DNA, and carbohydrates.
Water soluble polymers are polymers that will dissolve in water.
they are called polymers
