摘　　要：用ＴＹ－８２接触角测定仪测定了三氨基三硝基苯（ＴＡＴＢ）、氟聚合物与标准溶液的接触角，用几何平均法计算其表面张力，并用调和平均方程计算ＴＡＴＢ与不同氟聚合物的界面张力及粘附功。结果表明，ＴＡＴＢ与氟聚合物间界面张力及粘附功的大小主要由它们的极性匹配情况决定，极性越匹配，则界面张力越小，粘附功越大，粘接越牢固。The contact angles of water and glycerol to 1, 3, 5 - triamino - 2, 4, 6 - trinitrobenzene (TATB) and flu- oropolymer were measured by TY - 82 contact angle measarer.The sulface tension of TATB and fluoropolymer were calculated by geometry average method , the interfacial tension and adhesive work were calculated by harmonic average equation .The results show the TATB has small interfacial tension and big adhesive work to fluoropolymer when their polarity is matching very well.
