In this work Surface-Enhanced Raman Scattering (SERS) was used to probe the light emitting conjugated polymer F8-PFB at the single molecule level using nanoparticle on an extended metallic film nano-gap. The directional field enhancement of the nano-gap combined with Density Functional Theory (DFT) calculations was used to determine the orientation of the molecule. This analysis revealed that the spin-coated conjugated polymer preferentially aligns its molecular chains parallel to the metallic substrate. The integration of this approach in nanofabrication and synthesis will have a profound impact on different fields ranging from molecular electronic devices to biomedical applications.","PeriodicalId":20346,"journal":{"name":"Polymer science","volume":"333 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76595407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main objective of this study was using of changes in the electrical properties of nanocomposites in contact with various solvents, to produce a material for solvent sensing. TEM micrographs confirmed uniform distribution of the tubes within the polymer matrix and the formation of a conductive network. Electrical conductivity measurements showed a percolation threshold bellow 1 wt.% CNTs for this system. To investigate their sensing performance, the samples were immersed in four different solvents having solubility parameters close to that of PC. All solvents could reduce the electrical conductivity of the nanocomposites, however the magnitudes and time dependent characteristics of the conductivity change were distinct and different for each solvent. Therefore, these nanocomposite samples could be potentially used as solvent sensors. The effect of nanotube content and the type of solvent on the sensory behavior of the samples were studied.","PeriodicalId":20346,"journal":{"name":"Polymer science","volume":"75 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73929850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
