Despite interesting properties of polysiloxanes, such matrices were rarely used in combination with clay minerals. Thus, for the first time, a systematic study was designed to investigate the cross-linking efficiency of polysiloxane networks in the presence of 2 wt % of organo-montmorillonite. Montmorillonite (Mt) was intercalated with six quaternary ammonium salts of the cation structure [(CH3)2R\u2019NR]+, where R = C12, C14, C16, and R\u2019 = methyl or benzyl substituent. The intercalation efficiency was examined by X-ray diffraction, CHN elemental analysis, and Fourier transform infrared (FTIR) spectroscopy. Textural studies have shown that the application of freezing in liquid nitrogen and freeze-drying after the intercalation increases the specific surface area and the total pore volume of organo-Mt. The polymer matrix was a poly(methylhydrosiloxane) cross-linked with two linear vinylsiloxanes of different siloxane chain lengths between end functional groups. X-ray diffraction and transmission electron microscopy studies have shown that the increase in d-spacing of organo-Mt and the benzyl substituent influence the degree of nanofillers\u2019 exfoliation in the nanocomposites. The increase in the degree of organo-Mt exfoliation reduces the efficiency of hydrosilylation reaction monitored by FTIR. This was due to physical hindrance induced by exfoliated Mt particles.<\/jats:p>","DOI":"10.3390\/ma14102623","type":"journal-article","created":{"date-parts":[[2021,5,18]],"date-time":"2021-05-18T00:06:54Z","timestamp":1621296414000},"page":"2623","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":34,"title":["The Effect of Surfactant-Modified Montmorillonite on the Cross-Linking Efficiency of Polysiloxanes"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2672-4878","authenticated-orcid":false,"given":"Monika","family":"W\u00f3jcik-Bania","sequence":"first","affiliation":[{"name":"Faculty of Geology, Geophysics and Environmental Protection, AGH University of Science and Technology, al.
