Sensing the hygroscopicity of polymer and copolymer materials using terahertz time-domain spectroscopy.

چکیده
We present the hygroscopicity of polymer and copolymer materials in the low terahertz (THz) frequency range using a linear absorption model. We identify COC 6013 and COC 5013 as optimal THz window materials, possessing both low hygroscopicity and high transmission in the THz regime. The correct choice of window material is of significance for transmission THz spectroscopy and of particular interest for THz liquid spectroscopy.

Determination of additive content in polymeric compounds with terahertz time-domain spectroscopy
We present terahertz transmission time-domain spectroscopy measurements on a variety of additive-polymer combinations with differing additive contents. At lower terahertz frequencies, standard polymers are transparent. When processed into compounds, their terahertz properties are distinctively affected by additives in most cases. The materials under investigation are magnesium hydroxide in line...
متن کاملCharge generation in organic solar cell materials studied by terahertz spectroscopy
We have investigated the photophysics in neat films of conjugated polymer PBDTTPD and its blend with PCBM using terahertz time-domain spectroscopy. This material has very high efficiency when used in organic solar cells. We were able to identify a THz signature for bound excitons in neat PBDTTPD films, pointing to important delocalization in those excitons. Then, we investigated the nature and ...
متن کاملNondestructive Evaluation of Carbon Fiber Reinforced Polymer Composites Using Reflective Terahertz Imaging
Terahertz (THz) time-domain spectroscopy (TDS) imaging is considered a nondestructive evaluation method for composite materials used for examining various defects of carbon fiber reinforced polymer (CFRP) composites and fire-retardant coatings in the reflective imaging modality. We demonstrate that hidden defects simulated by Teflon artificial inserts are imaged clearly in the perpendicular pol...
متن کاملElectrical characterization of conducting polypyrrole by THz time-domain spectroscopy
Using an optoelectronic THz beam system for THz time-domain spectroscopy ~THz TDS!, we have measured the absorption and index of refraction of a conducting polypyrrole film from low frequencies to 2.5 THz. From these measurements, the dc conductivity of 215/~V cm! and the complex conductance were obtained over this frequency range. All of the results were well fit by Drude theory, which gives a...
متن کاملThe impact of nearest neighbor interaction on the resonances in terahertz metamaterials
By using terahertz time-domain spectroscopy and rigorous simulations, we investigate the impact of gap orientation of neighboring split rings on the three lowest order eigenmodes for a metamaterial based on split ring resonators. We distinct scenarios where neighboring split rings have their gap either on the same or on opposite sides. The two lowest order eigenmodes are marginally affected, wh...
