Presentation Transcript

  1. Welcome Smart Coatings 2006 Symposium Coatings Research Institute

  2. Smart Coatings A Short Overview J. Baghdachi, Ph.D. Jamil.baghdachi@emich.edu 734-487-3192

  3. Smart Coatings and Materials Materials, which are capable of adapting dynamically their properties to an external stimulus, are called responsive or “smart.” To view or download slides, please visit www.emich.edu/public/coatings_research/smartcoatings

  4. Smart Coatings and Materials Most synthetic materials follow a permanently defined path and behave statically The situation is fundamentally different in biology Living beings cope with continuous changes to survive. - Reshaping, reorganization and rebuilding-- bones - Dynamic and responsive– cell membranes

  5. Smart Coatings and Materials • One-way systems: Already in use • -Corrosion sensing • -Conductive coatings • -Anti-inflammatory coatings • Two-way systems: More challenging • -Shape-memory materials • -Hydrophobic/hydrophilic switching • -Thermochromic pigmented coatings

  6. Smart Coatings and Materials  Adaptive materials -Properties endure as long as the signal is present -Permanent signal • Switchable materials -Momentary signal

  7. Smart Coatings Stimuli • Chemical Signals •  Acid-base reactions •  Complexation •  Bond formation/breaking •  Electrochemical reactions •  Photochemical reactions Physical Signals  pH  Ionic strength  Temperature  Pressure/mechanical  Surface tension  Light and acoustic  Electrical/magnetic fields

  8. Examples of Smart Coatings  Antimicrobial and Hygienic  Antifouling  Bio-catalytic  Color shifting  Conductive  Corrosion sensing  Defect/degradation sensing  Light sensing  Molecular electronics  Nanotechnology-based  Optically active  Photo-catalytic  Pressure sensing  Shape-memory polymers  Self-lubricating  Self-repair and healing  Super hydrophobic  Thermally triggered

  9. Smart Coatings Smart coating is not just a dream some are already in use. To view or download slides, please visit www.emich.edu/public/coatings_research/smartcoatings

  10. Smart Coatings and Materials Commercially available! Conductive polymers and coatings  Anti-inflammatory/antimicrobial coatings  Nanotechnology-based coatings

  13. Smart Coatings Self-healing polymer in action. E. Brown, Univ. of Illinois, 2001

  14. Smart Coatings Autonomic Healing of Polymer Coatings Scott White, N. R. Sottos, University of Illinois at Urbana-Champaign

  15. Smart Coatings Autonomic Healing of Polymer Coatings Scott White, N. R. Sottos, University of Illinois at Urbana-Champaign, Urbana, USA

  16. Smart Coatings Alternative Approach: H2O hv, T Chemical reactions Self-healing J. Baghdachi, et al., work in progress

  17. Smart Coatings 2007 • February 21-23, 2007 • Orlando, Florida • Confirmed presentations as of Feb 1, 2006 • Self assembling coatings • Photonics • Corrosion sensing materials • Conductive coatings • Self-release coatings
