Abstract A new kind of laser energy convertor with highly improved photothemic performance was fabricated using a facile and versatile approach, which was composed of graphene oxide and polytetrafluoroethylene membranes. SEM, XRD and TG-DSC were performed to characterize and compare the morphology, composition and heat release of the different graphene oxide and polytetrafluoroethylene membranes. The optimized freestanding composite membrane exhibited highly improved photothermic temperature rise under the laser irradiation (from 132 °C to 236 °C), which was further used as the laser energy convertor for the laser ignition and largely reduced the threshold power for laser initiators (approximately 48%). These results can promote the development of superior laser energy convector and also laser initiators with low ignition energy.

用于激光点火的具有优异光热性能的独立氧化石墨烯-聚四氟乙烯膜

摘要 采用一种简便且通用的方法制备了一种新型的光热性能得到显着提高的激光能量转换器，它由氧化石墨烯和聚四氟乙烯膜组成。进行SEM、XRD和TG-DSC来表征和比较不同氧化石墨烯和聚四氟乙烯膜的形态、组成和放热。优化后的独立式复合膜在激光照射下（从 132°C 到 236°C）表现出极大改善的光热温升，进一步用作激光点火的激光能量转换器，并大大降低了激光引发器的阈值功率（约48%）。这些结果可以促进优异的激光能量对流器和低点火能量的激光引发器的发展。
