This project, conducted in partnership with FilSpec Inc., aims to characterize the optical properties and theheating power, under optical illumination, of a series of textile fabrics made from a blend of specialized yarns.These specialized yarns contain a certain proportion of carbon black and mineral nanoparticles, which areresponsible for their optical absorption in the visible and near infrared. Textiles with different combinations ofregular and near-infrared sensitive fibers will be tested to assess the impact of these mixtures on their heatingpower.Optical studies include measurements of transmittance and absorbance spectra in the 400 to 1500 nm range,under different illumination conditions. These measurements will be correlated with measurements oftemperature change under illumination. An exploratory study of the dynamics of the self-heating phenomenonwill be carried out using transient absorption measurements.

该项目是与FilSpec Inc.合作进行的，目的是表征一系列由特种纱线混纺而成的织物的光学性能和在光照射下的加热功率，这些特种纱线含有一定比例的炭黑和矿物纳米颗粒，它们负责它们在可见光和近红外的光吸收。将测试具有不同常规和近红外敏感纤维组合的纺织品，以评估这些混合物对其加热能力的影响。光学研究包括在不同照明条件下测量400至1500 nm范围内的透射率和吸收光谱。这些测量将与光照下温度变化的测量相关联。将利用瞬态吸收测量对自热现象的动力学进行探索性研究。
