Properties and Uses
- Different materials
have different properties
- The possible uses
for a material depend
on its propeties
- A product's properties depend
on the materials it's made from
- Asses the suitability of
different materials
- Uses of
Crude Oil
- Crude oil is a mixture
of Hydrocarbons
- Hydrocarbon Properties
change as the chain
gets longer
- Crude oil is separated
by fractional distillation
- Crude oil has
various uses
- Polymerisation
- Polymerisation means loads of
small molecules link together
- There are lots of
different types of
polymers
- Polymers have replaced
natural materials for some uses
- Structure and Properties of Polymers
- A polymer's properties
decide its uses
- Its properties depend on
how the molecules are
arranged and held together
- Polymers can be modified to
give them different properties
- Nanotechnology
- Nanomaterials
are very small
- Nanoparticles are often
designed for particular use
- Used to
modify
particles of
materials
- The effects on health are not fully understood
