Sensitivity optimisation of hybrid calixarene-reduced graphene oxide langmuir-blodgett thin films via langmuir, optical, structural and elektrical characterisations
Lim, Darwina Choo Kheng
The  study  aimed  to  investigate  the  characteristics  of  calixarene,  reduced  graphene oxide  (rGO) and their composite in order to optimise the sensitivity of the composite. The   calixarenes    (calix[4]arene,   calix[6]arene   and   calix[8]arene)   and   rGO   were prepared  in  solution   to  form  a  Langmuir  film  by  using  Langmuir-Blodgett  (LB) trough. The values of 30 mN/m and  15 mN/m were selected for calixarenes and rGO respectively  for  the  thin  film  deposition.  The   surface  potential  (?V)  and  effective dipole  moment  (µ?)  of  calixarenes  were  also   investigated.  The  optical  properties  of calixarene   in   solution   and   thin   film   were    studied   using   UV-Visible   (UV-Vis) spectroscopy  and  compared  to  ensure  the  stability  of   the  thin  film.  Meanwhile,  the rGO thin film was characterised with UV-Vis spectroscopy for t.....
