The temperature-dependent mechanical properties of polyethylene terephthalate (PET) polymers are investigated using force-distance curves, adhesion force, and atomic force microscope (AFM) nanolithography combined the heating techniques. The results show that the width of grooves on the polymers at 20-60 °C were in the range of 14-363 nm. The wear depth of the polymers increased with increasing heating temperature. A volume of 251.85-2422.66 μm(3) at a load of 30-50 nN with heating to 30-60 °C was removed, as compared to that of 26.60-70.30 μm(3) obtained at room temperature. The contact forces of PET started increasing at 9 nN, whereas the size of the holes was average at a pressure. The results may be of importance in explaining the heating relationship among adhesion force, volume removal rate, and pressure.
采用力-距离曲线、粘附力和原子力显微镜（AFM）纳米光刻技术结合加热技术，研究了聚对苯二甲酸乙二醇酯（PET）聚合物的温度相关力学性能。结果表明，聚合物在 20-60°C 下的沟槽宽度在 14-363nm 范围内。随着加热温度的升高，聚合物的磨损深度增加。与室温下获得的 26.60-70.30μm(3)相比，在 30-50nN 的载荷下加热到 30-60°C 时，聚合物的体积去除量为 251.85-2422.66μm(3)。PET 的接触力在 9nN 时开始增加，而孔的尺寸在压力下平均。这些结果对于解释粘附力、体积去除率和压力之间的加热关系可能具有重要意义。
