Copolysiloxane Langmuir-Blodgett Surface Potential Volatile Organic Compounds Link to publisher's homepage at http://ijneam.unimap.edu.my/ A quick detection for volatile organic compounds (VOCs), especially in the indoor environment is a must as the build-up level of VOCs is multiple times greater than outdoor environment. By using a surface potential probe, we have analyzed the interaction between copolysiloxane Langmuir-Blodgett (LB) thin films with several commercially used VOCs solvent, specifically chloroform (CHCl3), isopropyl alcohol (IPA) and dichloromethane (DCM). These copolysiloxane LB thin films, namely P50:50 and P25:75 had been deposited onto aluminium-coated substrates. Subsequently, the surface potential (ΔV) of copolysiloxane LB thin films were monitored during exposure to each solvent. Interaction of these thin films with each solvent produced non-identical changes in ΔV values. In addition, ΔVmax value and halftime response for half ΔVmax value (t50) were determined. Later, a figure of merit, ƒ was calculated to determine the optimum sensing material per solvent. The most promising candidates particularly as IPA solvent vapour sensors is P50:50 copolysiloxanes LB thin film that presented ΔVmax (106 mV), smallest halftime response for half ΔVmax value achieved, t50 (65 s), and considerable ƒ (1.631 mV/s), as compared to others. 2017-09-28T07:26:30Z 2017-09-28T07:26:30Z 2017 Article International Journal of Nanoelectronics and Materials, vol.10 (1), 2017, pages 39-46 1985-5761 (Printed) 1997-4434 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/49810 en Universiti Malaysia Perlis (UniMAP)
