| 英文摘要 | The effect of thermal treatment over a wide range of temperature (130-280 degrees C) on the crystallization behavior of nylon 6 was studied by using DSC, FTIR, and polarized light microscope equipped with a hot stage. The crystallization and the subsequent melting behavior of the nylon 6 samples treated at different temperatures (T-s) were classified into four types. When T-s was higher than 236 degrees C or lower than 213 degrees C, the crystallization behavior of nylon 6 was insensitive to the variation of T-s. When T-s was in the range of 213-235 degrees C, the crystallization behavior was sensitive to the change of T-s. The polarized light microscopic experiments have demonstrated that a large amount of tiny ordered nylon 6 segments/cluster persisted when nylon 6 film are heated to 231 degrees C. Consequently, the fastest crystallization speed was observed. As T-s was between 214 and 223 degrees C, both the T-m and the Delta H-m were higher than those of the nylon 6 samples treated at other temperature. The polarized light microscopic investigations have also demonstrated that molten nylon 6 crystallizes by using the un-molten nylon 6 crystals as nucleation center at 220 degrees C. Crystallization at higher temperature produces nylon 6 with thicker crystalline lamella. The above results are helpful for rational design of thermal treatment procedure to obtain nylon 6 with different crystalline features. (C) 2015 Wiley Periodicals, Inc. |
