Investigating the effect of water-mixing nitrogen atmospheric pressure plasma jet on polyether-ether-ketone and time stability under different conditions
Possessing excellent properties including good biocompatibility, high strength, and stiffness, polyether-ether-ketone (PEEK) has significant application values in medical and industrial fields. However, the relatively poor wettability and low adhesion limit its further applications. Atmospheric pressure plasma jet (APPJ) has been utilized for adjusting PEEK properties, but better hydrophilization effect and time stability after treatment are still urgently needed. In this paper, we employ a water-mixing nitrogen (N-2-H2O) APPJ to process PEEK, and surface wettability can be effectively improved (contact angle similar to 18 degrees within 2 min, distance between sample and nozzle outlet: 10 mm) without inducing obvious microstructure damages. Additionally, after storing for 40 days, the sample treated by N-2-H2O APPJ also possessed better wettability (similar to 54 degrees) compared with that treated by N-2 APPJ (similar to 65 degrees). On the basis of this low-damage and high-efficient modification method, we perform aging experiments under different conditions (different temperatures 25, -10 degrees C; and low vacuum condition: 50 kPa) to determine a relatively optimum storing condition for this method. The experiment results indicate that low temperature and vacuum are conducive to retaining the plasma-induced wettability (similar to 34 degrees). The treatment method and storing conditions for PEEK presented here may facilitate the application of PEEK in various fields.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 103-50-4, you can contact me at any time and look forward to more communication. Category: ethers-buliding-blocks.
