  1. 1. Biopolymers
  2. 2. arunraj(kudiyan) jabir kv ijaz(annan) binaz(thavala) shiju vp
  3. 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. 4. POLYMERS•Polymers - long chain molecules of highmolecular 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
  5. 5. Common Polymer Biomaterials
  6. 6. Polymers In Specific Applications
  7. 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
