However, this technique performed unsatisfactorily as it reduces the surface free energy and affects the gas relative permeability negatively. Hence, alternative surface-modified nanoparticles using fluorine-based chemicals were developed as wettability alteration agents since fluorine exhibits a high degree of liquid repellency and nanoparticles introduce high surface roughness. The newly synthesized surface-modified nanoparticles were characterized using FTIR, DLS, FESEM, and TGA. FTIR results highlight the characteristic absorption of Si-O-C group at peak 1105 and 1106 cm-1 in both fluoroalkanoic acids, demonstrating that fluorochemical molecules have been successfully coated onto silica nanoparticles. Nanoparticle sizes measured by DLS reported higher value than FESEM due to agglomeration, and the DLS measurement was done in hydrodynamic conditions. TGA analysis reveals decomposition at temperature between 100 and 150°C, indicating that these surface-modified nanoparticles can be utilized in an environment below 100°C. Higher decomposition was perceived on PFNA-modified nanoparticles as a thicker coating of PFNA is shrouding the silica nanoparticles compared to PFOA. Implications of the results will path the way for future research direction in using fluorine-based surface-modified nanoparticles as wettability alteration agents. © 2020 Kenny Ganie et al. date: 2020 publisher: Hindawi Limited official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85094888048&doi=10.1155%2f2020%2f8814260&partnerID=40&md5=ba41cbde37384bfe160b5f9145cd2b64 id_number: 10.1155/2020/8814260 full_text_status: none publication: Journal of Nanomaterials volume: 2020 refereed: TRUE issn: 16874110 citation: Ganie, K. and Mohshim, D.F. and Saaid, I.M. and Sulaiman, W.R.W. and Idris, A.K.
