This study presents a novel approach to further augment the hydrophobicity of ZSM-5. The ZSM-5 zeolite molecular sieve was subjected to modification using three different silane coupling agents, namely, n-octyltriethoxysilane (OTES), \u03b3-methacryloxypropyltrimethoxysilane (KH-570), and \u03b3-aminopropyltriethoxysilane (KH-550). The water contact angles of the resulting OTES@ZSM-5, KH-570@ZSM-5, and KH-550@ZSM-5 particles exhibited significant increases from 97.2\u00b0 to 112.8\u00b0, 109.1\u00b0, and 102.7\u00b0, respectively, thereby indicating a notable enhancement in hydrophobicity. Subsequently, mixed matrix membranes (MMMs) were fabricated by incorporating the aforementioned silane-modified ZSM-5 particles into polydimethylsiloxane (PDMS), leading to a considerable improvement in the adsorption selectivity of these membranes towards trichloroethylene (TCE). The findings indicate that the PDMS membrane with a 20 wt.% OTES@ZSM-5 particle loading exhibits superior pervaporation performance. When subjected to a temperature of 30 \u00b0C, flow rate of 100 mL\/min, and vacuum of 30 Kpa, the separation factor and total flux of a 3 \u00d7 10\u22127 wt.% TCE solution reach 328 and 155 gm\u22122\u00b7h\u22121, respectively. In comparison to the unmodified ZSM-5\/PDMS membrane, the separation factor demonstrates a 41% increase, while the TCE flux experiences a 6% increase. Consequently, this approach effectively enhances the pervaporation separation capabilities of the PDMS membrane for TCE.<\/jats:p>","DOI":"10.3390\/polym15183777","type":"journal-article","created":{"date-parts":[[2023,9,17]],"date-time":"2023-09-17T23:25:26Z","timestamp":1694993126000},"page":"3777","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Improving the Pervaporation Performance of PDMS Membranes for Trichloroethylene by Incorporating Silane-Modified ZSM-5 Zeolite"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4522-9143","authenticated-orcid":false,"given":"Xiaosan","family":"Song","sequence":"first","affiliation":[{"name":"School of Environmental and Municipal Engineering, Lanzhou Jiaotong University, Lanzhou 730070, China"},{"name":"Key Laboratory of Yellow River Water Environment in Gansu Province, Lanzhou Jiaotong University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xichen","family":"Song","sequence":"additional","affiliation":[{"name":"School of Environmental and Municipal Engineering, Lanzhou Jiaotong University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yue","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Environmental and Municipal Engineering, Lanzhou Jiaotong University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-3303-9603","authenticated-orcid":false,"given":"Jishuo","family":"Fan","sequence":"additional","affiliation":[{"name":"School of Environmental and Municipal Engineering, Lanzhou Jiaotong University, Lanzhou 730070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2180","DOI":"10.1039\/c3gc40291f","article-title":"Preparation of PDMS membrane using water as solvent for pervaporation separation of butanol\u2013water mixture","volume":"15","author":"Li","year":"2013","journal-title":"Green Chem."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"133","DOI":"10.1016\/j.jchromb.2016.12.034","article-title":"Zeolite-loaded poly(dimethylsiloxane) hybrid films for highly efficient thin-film microextraction of organic volatiles in water","volume":"1041\u20131042","author":"Wang","year":"2017","journal-title":"J.
