Polymers and their uses
A polymer is easily recognized as
a valuable chemical substance made up of a number of replicate units. The basic
replication unit of a polymer is referred to as the "-mer" with the
"polymer" denoting a chemical made up of many replicating wholes.
Polymers applications
Polymers can be chemically synthesized
in a variety of ways depending on the chemical feature of the monomer thus
material body ing a desired product. Nature affords many example of polymer
which can be used directly or transformed to form stuff required by society
serving specific needs.
The polymers of concern are generally composed of
carbon and hydrogen with extension to O , nitrogen and chlorine
functionalities. Chemical electrical resistance , thermal and electrical
insulation, strong and luminousness -weight, and myriad application s where no
alternative exists are polymer characteristics that continue to make polymers
attractive.
Significant polymer application can be found in the automotive,
building and construction, and packaging diligence .
Some device characteristic also build prominently in the
environmental lifespan of polymers or credit card .
Recently, reputation of
microbial abjection of polymeric fabric offer new emerging technological
opportunities to modify the enormous pollution scourge incurred through use of
polymers/charge card .
Polymers and polymer composites
A significant lit exists from which developmental
direction for possible biological technologies can be discerned. Each report of
microbial mediated degradation of polymers must be characterized in detail to
provide the database from which a new applied science developed.
Contribution
of the development must address the kinetics of the degradation process and
uncovering new approaches to enhance the pace of degradation. The understanding
of the interaction of biotic and abiotic degradation is implicit to the applied
science development travail.
The properties have demonstrated the general utility of
polymer and their manipulation for mental synthesis of a multitude of widely
useful items leadership to a world saturation and recognition of their
unattractive properties too.
A John Major drift of ever increasing consumption
of plastic s has been seen in the country of industrial and domestic
applications. Much of this polymer production is composed of plastic materials
that are generally non-biodegradable. This widespread use of plastics raises a
significant threat to the surround due to the lack of proper waste direction
and a until recently Cavalier community behavior to maintain proper controller
of this waste stream.
Polymers classification
Response to these stipulation has elicited an effort to
devise innovative strategies for plastic waste management , invention of
biodegradable polymer , and education to promote proper disposal.
Engineering available for current polymer abjection strategies are chemical, thermal ,
photo, and biological techniques. The physical properties departure in density but remarkable conflict in crystallinity and
life . Crystallinity has been shown to play a very directing role in certain bio-degradation processes on select polymer.
