본문내용
Conjugated organic semiconductors
Expansion or contraction of the polymers by mobile solvated ions
Applied to several microsystems and actuated catheters, circulation pumps, etc.
Low level charge injection Quantum mechanical effects dominate
High level charge injection Coulomb forces dominate
Repulsive force between same charges
Discharging process
when approach high potential,
begin to exchange ions
this makes maximum strain limit
Advantages of CNT as an actuator
- High output stress (work)
- Actuatable at high temperature (> 100℃ - ionic liquid)
- Double layer charge effect
long life-cycle (than conducting polymer)
Disadvantage
Low electrochemical strain (< 1%)
(than conducting polymer – polypyrrole 26%)
