I want to coat a uniform layer of monomers (dissolved in THF) onto TiO2 NWs (as a shell), but I could not use the electrodepostion method. I tried to drop it onto TiO2, but it always not uniform. So, is there any other way? Thanks
Just to echo Yujin - if your nanowires are tethered to a substrate then spin-coating is an excellent option. It's cheap, widely used in labs, reproducible and relatively simple, although you will have to optimise parameters such as solution concentrations and spin speeds/times to achieve your desired coating thickness. If you haven't got access to a spin coater then you could try dip coating - it's simple and quite widely used.
As Ivana said, plasma polymers are great. One major plus side about plasma polymers is that you should be able to tune the degree of cross linking in the polymer to create more robust coatings, or optimise with respect to subsequent processes. It could be difficult to achieve in practice though. Firstly, you will need access to a suitable plasma reactor. Secondly, if your monomer hasn't been studied in the past via plasma coating then it's suitability would need to be assessed and the coating process optimised. It is very easy to destroy organic molecules by excessively bond-breaking or cross-linking the monomers during the plasma coating if this is not done properly.
