| Abstract Scope |
Adherent carbon coatings on flexible polymeric substrates are necessary for state-of-the-art flexible electronic and health monitoring applications. Highly adherent Si-containing DLC films have been fabricated on flexible HDPE substrates using plasma-enhanced chemical vapor deposition technique. Plasma etching makes the surface of HDPE flat and opens up the surface bonds. Scratch test reveals 10 mN as the critical load for coating particle removal. The TEM analysis also confirmed excellent DLC adhesion to film substrate. The contact angle for HDPE increased from 90o to 110o when it was coated with Si-DLC. Further, these amorphous carbon coatings showed improvement in the adhesion, hydrophobicity and electrical conductivity after non-equilibrium laser annealing due to an increase in the amount of sp2 bonded carbon. This study provides useful information for modifying the properties of carbon thin films on flexible polymers for desired applications. |
