Manufacture of Thiophene Polymer Nanocomposite Coatings SBA15 and Its Application in the Extraction of Essential Oil of Melissa officinalis L.

In this work, a highly porous fiber coated with polythiophene on hexagonally ordered silica nanocomposite (PT/SBA-15) was prepared and used for extraction of essential oils. The prepared nanomaterials were immobilized on a stainless steel wire for fabrication of the SPME fiber.1 40 compounds were separated and identified in Melissa officinalis which mainly included Geranial (34.4%), Neral (20.14%), Cis-Chresontynol (3.45%), and Trans Rose oxide (2.83%). The experimental results showed that the polythiophene/hexagonally ordered silica nanocomposite fibers were suitable for the semi-quantitative study of the composition of essential oils in plant materials and monitoring the variations in the volatile components of the plants.2 In comparison to an HD method, the proposed technique could equally monitor almost all the components of the sample, in an easier way, shorter time and requiring a much lower amount of sample.
