What are you doing this evening?
Whatever
you have planned, you can be sure it will involve lots of things produced
by the chemical industry, things we all take for granted. Shopping or
swimming, gardening or golfing, painting
the bedroom or playing with the children, baking a cake or watching a
movie, chemistry will be on hand, helping to make our world more colourful,
more efficient, more reliable and much safer - and saving us money.
or another man-made fibre. Beneath your feet will be a carpet, similarly
treated, and made wholly or in part from similar hard-wearing fibres.
The
room will probably be decorated with acrylic paints and vinyl wall covering.
It may be lit with long-life bulbs in which some of the chemicals are
the same as those in the screen of your television set. This, along with
the video and CD player, will be housed in a safe and durable plastic
frame. Yet other forms of plastics are used for the cabling and plugs
that supply the electricity. Your video tapes, audio tapes and CDs are
made almost entirely from polymers.
The
weekend is often the time we become most aware of one type of plastic:
the plastic of credit cards. These colourful rectangles, usually of PVC
but sometimes of a biodegradable plastic invented by British chemists,
make spending so easy (too easy sometimes). Smart cards are the same size
and shape but are designed to carry lots more information, helping to
defeat thieves and, perhaps, save lives through the use of essential medical
data encoded in the chip.
Of
course chemistry will be the last thing on your mind as you get ready
to go out, but it is there as you shower and shampoo your hair, and it
is there as you put on your clean dress. The softness and fresh smell
of clean clothes rely on some rather clever chemistry. And it does not
stop there. Perfumes and cosmetics, too, are designed and made by chemists.
By the time you are ready to go out you should be feeling good and looking
good. You may even have changed the colour of your eyes with disposable,
tinted contact lenses made mainly from purified water and acrylic resin.
