流变仪和傅里红外光谱仪同步测量研究紫外线诱导的固化反应English

In many industrial segments the use of UV curing materials for the processing or application of paints, inks, adhesives, coatings, etc. is of upmost importance. This technology combines environmental and economical advantages with improved product features.A curing process can be followed by dynamic rheological measurements, since the build-up of a network in the sample is directly related to the change of the viscoelastic properties (G’, G“, etc.) of that sample.By combining oscillatory rheological measurement with a second analytical  technique an even more comprehensive insight into the characteristics of curing processes can be achieved. Such a supplemental tool can be e.g. FT-IR spectroscopy. For a curing  process or phase transition in general a rheometer can analyze the time dependent change of the viscoelastic properties of a material. The viscoelastic properties of a material however depend on its structure and especially its structural changes during a curing process. Infrared spectroscopy is an excellent tool for determining structural changes on a molecular level.
We will present technical details of new UV-curing se-tup for the Thermo Scientific MARS rheometer and show the experimental results of the investigation of an UVcuring processes for an acrylate based coating for optical fibers. The presented data includes rheological as well as spectroscopic data.
