The IR spectra of a number of standard polymers, such as polytetrafluoroethylene (PTFE), polystyrene (PS), polypropylene (PP), and polyethylene (PE), are shown in Figure 1. The PerkinElmer Spectrum ...

When a plastic absorbs IR radiation, it produces a spectrum representative of its molecular ... bag sample was identified (using the spectral library) as high-density polyethylene (HDPE) with a 94% ...

Here, Po-Chun Hsu, Yi Cui and colleagues explored an existing nanoporous polyethylene (nanoPE), evaluating whether it would allow IR-radiation to pass through, and thus make a likely cool clothing ...
