中文摘要:
      目的 制备聚酰亚胺(PI)/羰基铁粉(CI)复合膜并探究其性能,以改变微波加热过程中的加热方式。方法 主要通过红外光谱、扫描电镜、力学性能、透氧透湿和微波转热测试分析其性能。结果 聚酰亚胺与羰基铁粉是物理结合;当羰基铁粉质量分数超过25%时,开始发生团聚;当羰基铁粉质量分数为20%时,弹性模量最小;当羰基铁粉质量分数为15%时,透氧透湿系数最低;随着羰基铁粉含量的增加,复合膜在微波加热下升温和常温下降温的速率增加。结论 PI/CI复合膜能够吸收部分微波转热能,是一种新型的吸波包装材料,为微波加热用包装材料的设计提供了新思路。
英文摘要:
      In order to change the heating mode in microwave heating process, polyimide (PI)/carbonyl iron powder (CI) composite film was prepared and its properties were investigated. The properties of the composite film were analyzed by infrared spectroscopy, scanning electron microscopy, mechanical properties, oxygen permeability and moisture permeability and microwave heating. The results showed that the addition of carbonyl iron powder to polyimide was physically binding. When the content of carbonyl iron powder exceeds 25%, agglomeration begins to occur. It was found that the elastic modulus was the smallest when the content was 20%. When the content was 15%, the oxygen permeability and moisture permeability coefficient was the lowest. With the increase of carbonyl iron powder content, the rate of heating and cooling of the composite film under microwave heating increased. The conclusion is that PI/CI composite film can absorb microwave energy to heat energy, which is a new type of absorbing packaging material and provides a new idea for packaging material design in microwave heating process.
