2.1 Introduction
Before the discovery of plastics, elephant ivory (teeth and tusks) obtained from the
remains of elephants have found applications in the manufacturing of billiard balls,
combs, and many products. To meet the market demand for elephant ivory, the killing of the elephants has become widespread such as in the African continent that the
elephant population has dramatically decreased. The ivory products consequently
become prohibitively expensive. Thus, the alternative material was invented by J. W.
Hyatt and his brother from cotton cellulose and named as “Celluloid” (National
Museum of American History, Estate of Catherine Walden Myer). The word “Plastic” was coined from the Greek word “Plastikos” which means “moulded or
shaped by heat” for the celluloid-like product easily moulded into different shapes.
A big disadvantage in the preparation of the cellulose-based products is the exothermic reaction of the mixture which produces high energy and releases heat making it
potentially highly flammable and risky.
An American chemist, L. Baekeland, considered as “the Father of the Plastic
industry,” has successfully synthesized bakelite, prepared using phenol from coal tar
and formaldehyde and reacted together. Bakelite has a good property for insulation.
The invention of bakelite opens up a new avenue for the development of plastics, its
derivatives, and composite materials for specialized applications in most areas in the
fields of material sciences. Plastics are durable and sometimes inert, which can
withstand very harsh conditions of temperature and weathering. These properties
of plastics make it a burden to the environment later, after use.
