英文摘要 | Due to the hydrophobic nature and high gravimetric density, it is very difficult to obtain water dispersible polytetrafluoroethylene (PTFE) powder. In this work, hydrophilic PTFE microparticles were successfully prepared by grafting of poly(acrylic acid) onto PTFE micropowder via a pre-irradiation method. The as-obtained hydrophilic PTFE microparticles were analyzed by FT-IR, H-1 NMR, CA, SEM and TGA. After neutralization by sodium hydroxide, the water contact angle decreased from 145.69 degrees for pristine PTFE to 63.38 degrees for PTFE-g-NaAA. The obtained micropowder can be easily dispersed in water to form a dispersion with very high stability. Furthermore, the presence of grafted PAA shows no obvious influence on degradation temperature of PTFE backbones. (C) 2014 Elsevier Ltd. All rights reserved. |
