3. Polymer Biomaterials
• There are a large number of uses for polymers
in the biomaterials field. These arise due to
the wide variety of properties possible.

4. POLYMERS
•Polymers - long chain molecules of high
molecular weight n State Use
-(CH2)n- 1-4 gas burned for energy
5-11 liquid gasoline
9-16 med. visc. kerosene
liquid
16-25 hi visc. liq. oil, grease
25-50 solid paraffin wax
1000- tough plastic PE bottles, containers
3000

7. The Bulk State : Solid
•Polymers can be either amorphous or semi-
crystalline, or can exist in a glassy state.
•amorphous glassy state
– hard, brittle
– no melting point
•semi-crystalline glassy state
– hard, brittle
– crystal formation when cooled
– exhibit a melting point
