Man-made Synthetic Polymers, Bio-fibres, Nano-technology

Man-made Synthetic Polymers

Scientists have used biosynthetic muscle fibers to observe the changes that polymers exhibit when subjected to mechanical stress.

scientists, as a result of extensive research, were able to replicate naturally occurring animal and plant fibers by creating fibers from synthetic chemicals. In the literature, it is often noted that there are three kinds of man-made fibers: those made by “transformation of natural polymers” (also called regenerated cellulosics), those made from synthetic polymers and those made from inorganic materials (These include the fibers made of glass, metal, ceramics and carbon.) But by far the largest group of man made synthetic fibers being produced today are made from synthetic polymers, so we’ll concentrate on those in this post.


Bio-fibres


Stemergy bio-fiber is focused on producing and supplying renewable bio-fibres - derived from annual stem fiber plants such as flax and hemp – to the expanding global bio-fiber marketplace.The demand for renewable bio-fibers is quickly accelerating as they become the material of choice for a broad range of applications. In the era of rising fossil fuel and energy prices, using annual plants such as hemp and flax that convert solar energy and green house gases to produce useful renewable bio-fiber materials for manufacturing makes good economic and environmental sense.


Nano-technology

Nanotechnology (sometimes shortened to "nanotech") is the manipulation of matter on an atomic and molecular scale. Generally, nanotechnology works with materials, devices, and other structures with at least one dimension sized from 1 to 100 nanometres. Quantum mechanical effects are important at this quantum-realm scale.
