摘要
Abstract
Polytetrafluoroethylene ( PTFE) was activated with the mixture solution of tert-Butyllithium (t-BuLi) and ethylenediamine ( EDA) , and grafted GMA onto the PTFE. The chemical structure of activated and grafted PTFE was analyzed by using FTIR. It shows that GMA was successfully grafted onto the PTFE. SEM was used to observe the surface morphology of grafted PTFE. The grafting ratio of 5. 83% was achieved, which was measured by TGA. The effect of reaction time and temperature for the grafting ratio was studied finally. The grafting ratio was increased with the elongation of reactive time, and basically constant after 8h. The grafting ratio reaches its maximum when the reaction temperature is 70℃.关键词
