  • Silk
Q.8
Which below are natural polymers?
  • Cellulose
  • Nylon
  • Silk
  • Polyester
Q.9
One explanation for Teflon's low coefficient of friction, hydrophobic and biologically inert properties is.
  • The electronegativity of Fluorine
  • The thin, smooth surface is impossible for another molecule to create a cross-link
  • The IMF of the individual monomers in the structure make it difficult for other molecules to bond.
  • The highly branched and cross-linked nature of the polymer doesn't create any areas of adhesion for other molecules.
