Here, we investigate an interface-based strategy for influencing SiC polytype evolution by introducing compositionally complex TiVCrMoC3 MXene nanosheets at the preceramic stage. Under spark plasma sintering (1900 \u00b0C, 70 MPa), which typically stabilizes cubic 3C-SiC (\u03b2-SiC), the MXene partially transforms into multicomponent (Ti,V,Cr,Mo)Cx carbide structures, while MXene-derived layered regions are also locally observed. Local HRTEM observations show reconstructed carbide\/SiC interfaces adjacent to 6H-SiC regions and MXene-derived layered phase\/SiC interfaces adjacent to 3C-SiC regions, revealing heterogeneous interfacial configurations within the SiC matrix. Mechanical testing further reveals peak performance at an optimal MXene loading where interfacial reconstruction is most pronounced, with an \u223c82% increase in Young\u2019s modulus and \u223c42% improvement in fracture toughness. These findings highlight interfacial polytype engineering via two-dimensional carbide templates as a promising route for directing crystal structure evolution in polymer-derived ceramics.<\/jats:p>","DOI":"10.1021\/acsami.6c06733","type":"journal-article","created":{"date-parts":[[2026,10,6]],"date-time":"2026-10-06T09:01:21Z","timestamp":1791277281000},"page":"55265-55274","source":"Crossref","is-referenced-by-count":0,"title":["Interfacial Polytype Engineering of Polymer-Derived SiC via Compositionally Complex MXene Templating"],"prefix":"10.1021","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-9820-5102","authenticated-orcid":true,"given":"Yuxiang","family":"Gan","sequence":"first","affiliation":[{"name":"Texas A&M University , , , ,","place":["College Station, Texas, USA, 77843"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianyu","family":"Dai","sequence":"additional","affiliation":[{"name":"Texas A&M University , , , ,","place":["College Station, Texas, USA, 77843"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laxmi Sai","family":"Viswanadha","sequence":"additional","affiliation":[{"name":"Texas A&M University , , , ,","place":["College Station, Texas, USA, 77843"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Congjie","family":"Wei","sequence":"additional","affiliation":[{"name":"Texas A&M University , , , ,","place":["College Station, Texas, USA, 77843"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kelvin Y.","family":"Xie","sequence":"additional","affiliation":[{"name":"Texas A&M University , , , ,","place":["College Station, Texas, USA, 77843"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4150-5254","authenticated-orcid":true,"given":"Jeremy Lee","family":"Watts","sequence":"additional","affiliation":[{"name":"Missouri University of Science and Technology , , , ,","place":["Rolla, Missouri, USA, 65409"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1841-7598","authenticated-orcid":true,"given":"Mohammad","family":"Naraghi","sequence":"additional","affiliation":[{"name":"Texas A&M University , , , ,","place":["College Station, Texas, USA, 77843"]},{"name":"Texas A&M University , , , ,","place":["College Station, Texas, USA, 77843"]},{"name":"Texas A&M University , , , ,","place":["College Station, Texas, USA, 77843"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7733-1084","authenticated-orcid":true,"given":"Chenglin","family":"Wu","sequence":"additional","affiliation":[{"name":"Texas A&M University , , , ,","place":["College Station, Texas, USA, 77843"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,10,6]]},"reference":[{"issue":"1","key":"2026101408071382200_cit1","doi-asserted-by":"publisher","first-page":"39","DOI":"10.1016\/j.snb.2010.09.059","article-title":"Advances of SiC-based MOS capacitor hydrogen sensors for harsh environment applications","volume":"151","author":"Soo","year":"2010","journal-title":"Sens.
