Near?infrared light for polymer re?shaping and re?processing applications

نویسندگان

چکیده

The re-shaping and reprocessing of polymers are usually associated with strong energetic costs, strongly limiting their practical usage. In this article, a new approach is proposed based on near-infrared (NIR) activation the material in presence NIR heater for highly efficient process upon ecofriendly light emitting diodes irradiation. Markedly, due to light-triggered process, spatial control shaping/reprocessing behavior can be obtained, that is, only needed parts irradiated preventing heating all sample. work, different thermoplastics reshaped or reprocessed an organic dye used as heater. As other examples photothermal treatment light, on-demand dehydration polyethylene glycol (PEG-based) hydrogels also provided. All processes followed real time by thermal imaging camera.
