“…This is due mainly to the reinforcing effect of organomontmorillonites and graphene nanosheets. The increase in rigidity (G′) was more marked in the range of temperatures lower than glass transition (Tg) of the PLA, contrary to what was reported in the case of the polypropylene/graphene nanocomposites (Milani et al, 2013). At 30°C, the PLA's modulus increased from 1.66 GPa to approximately 2.65 GPa in PLA filled with 3 phr of Cloisite® 15A, Cloisite® 30B, and graphene.…”

“…In this method, polyolefin/graphene nanocomposites are prepared by using the propylene or ethylene monomer and different types of catalysis such as metallocene complex rac-Me 2 Si (Ind) 2ZrCl 2 catalyst and methyl aluminoxane as cocatalyst [90,91], Ziegler-Natta catalyst [92], and Ni(II) catalyst precursor [93]. This technique results in a stronger interfacial interaction and better miscibility of graphene layer within the polyolefin matrix.…”

“…A adição de monômero olefínico leva à síntese de cadeias poliméricas exclusivamente localizadas nos arredores da superfície do NTC que, com o aumento de massas moleculares, precipita-se sobre os nanotubos, cobrindo-os e levando a uma eficiente desaglomeração [1,17,22] . Nos últimos anos nosso grupo de pesquisa vem trabalhando na obtenção de nanolâminas de grafeno (NG) (empilhamento de poucos grafenos) através de esfoliação química e térmica da grafite e na preparação de nanocompósitos de polietileno (PE) [25,26] e de polipropileno (PP) [27][28][29] utilizando a técnica de polimerização in situ. Nosso primeiro trabalho nesta área [25] , foi citado em uma recente revisão [30] como sendo o primeiro utilizando esta técnica para obter nanocompósitos de PE/NG.…”

Resumo: Nanocompósitos de polietileno/nanotubos de carbono foram sintetizados através da polimerização in situ para serem comparados com nanocompósitos de polietileno/nanolâminas de grafeno, obtidos nas mesmas condições. Os nanocompósitos de polietileno/NTC foram obtidos com boas atividades catalíticas e foram caracterizados por DSC e MET. Os nanocompósitos com NG apresentaram melhor estabilidade térmica que os de NTC, porem não houve diferenças significativas nas propriedades dinâmico-mecânicas. No estudo da condutividade elétrica os nanocompósitos PE/NTC atingiram condutividades de materiais semicondutores com menor teor de nanocarga que os de PE/NG. Palavras-chave: Nanolâminas de grafeno, nanotubos de carbono, polietileno, nanocompósitos. Comparison between Polyethylene/Carbon Nanotubes and Polyethylene/Graphene Nanosheets Nanocomposites Obtained by In Situ Polymerization Abstract: Polyethylene/carbon nanotubes, PE/NTC, nanocomposites were synthesized by in situ polymerization for comparison with polyethylene/graphene nanosheets, PE/NG, nanocomposites obtained in the same conditions. The nanocomposites of polyethylene/NTC were obtained with good catalytic activities and were characterized by DSC and TEM. The nanocomposites with NG showed better thermal stability than with NTC, however, no significant differences in dynamic mechanical properties were found. In the electrical conductivity study, PE/NTC nanocomposites reached conductivities of semiconductor materials at lower content of filler than PE/NG nanocomposites.
