Controlled synthesis of train-structured montmorillonite/layered double hydroxide nanocomposites by regulating the hydrolysis of polylactic acid

Montmorillonite-Based Two-Dimensional Nanocomposites: Preparation and Applications

“…There are two key challenges in the preparation of composite materials by intercalation methods. One is how to develop an effective method to peel off the laminated composite completely, and the other is how to adjust and control the assembly of nanosheets to obtain the nanocomposite with specific structure [ 50 ]. Before stripping, some methods require the materials to be modified in advance, so as to facilitate better stripping of the sheets in the stripping agent [ 51 ].…”

“…In addition, some researchers used biodegradable materials such as polylactic acid (PLA) for lamellar peeling. Hu et al [ 50 ] completely and effectively exfoliated LDH and Mt in PLA by melt blending for 10 min, and the resulting exfoliated monolayer molecules of Mt or LDH could be stably stored in PLA for a long time (SEM image of exfoliated LDH is illustrated in Figure 2 d). Table 1 summarizes common delamination methods.…”

A Doubly Confined Nickel‐Based Catalyst Derived from Hydrotalcite‐Montmorillonite Composite: Preparation and Hydrogenation Performance

“…It has a large layer distance, good thermal stability, and adjustable acidity, and has been used as catalyst support and adsorbent. However, its layers are too thick, making the catalytic active sites deeply encaged and thus hindering their catalytic activity [19,20] . To the best of our knowledge, there is few reports on the fabrication of a catalyst using the hydrotalcite‐montmorillonite composite as support or precursor [21] .…”

Desenvolvimento e caracterização de bionanocompósitos de poli(ácido) lático e argila montmorilonita incorporados com óleo essencial de melaleuca

“…O avanço da nanomedicina e da nanotecnologia tem possibilitado a criação de coberturas que entregam fatores de crescimento, terapias celulares, terapias genéticas e agentes antimicrobianos que estimulam a cicatrização (JAHROMI et al, 2018). A argila montmorilonita (MMT) é uma nanoargila bastante investigada para atuar como carregadora desses compostos ativos.…”
