These pristine and silane\u2010decorated mesoporous MCM\u201041s are further used in the synthesis of MCM\u201041\/ethylene nanocomposites by in\u2005situ polymerization, utilizing either supported or non\u2010supported catalytic systems. The catalytic behavior of those systems is discussed, taking into consideration the effects of the particle size, surface characteristics, and functionalization. The results have shown that the initial surface state of MCM\u201041 is of paramount importance to achieve high catalytic activity if a polymerization catalyst is to be supported. Functionalization changes the surface chemistry, thus, a positive or negative effect may be observed, depending on the previous features of the surface. The particle size of MCM\u201041 and its functionalization affect its final dispersion within the polymeric matrix, this distribution is evaluated by SEM, TEM, and microhardness measurements.<\/jats:p>","DOI":"10.1002\/cctc.201200639","type":"journal-article","created":{"date-parts":[[2012,11,26]],"date-time":"2012-11-26T21:56:20Z","timestamp":1353966980000},"page":"966-976","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["Functionalization of Mesoporous MCM\u201041 (Nano)particles: Preparation Methodologies, Role on Catalytic Features, and Dispersion Within Polyethylene Nanocomposites"],"prefix":"10.1002","volume":"5","author":[{"given":"A.","family":"Bento","sequence":"first","affiliation":[]},{"given":"J.
