“…Most published research works use a lab-scale melt mixer to melt PLA and mix it with the nanofillers. Typical processing conditions correspond to temperatures between 160 °C and 180 °C [ 160 , 161 , 162 , 163 , 164 , 165 , 166 ], mixing times of 5 to 10 min [ 160 , 161 , 162 , 164 , 165 , 167 ], and rotation speeds between 50 and 100 rpm [ 160 , 161 , 162 , 163 , 164 , 166 , 167 , 168 , 169 ]. After mixing, the composite materials are almost always molded into flat sheets with controlled thickness in a hot press, however, other methods are also used (e.g., injection molding and piston spinning).…”

Poly(lactic acid) Composites Containing Carbon-Based Nanomaterials: A Review

et al. 2017

View full text Add to dashboard Cite

Poly(lactic acid) (PLA) is a green alternative to petrochemical commodity plastics, used in packaging, agricultural products, disposable materials, textiles, and automotive composites. It is also approved by regulatory authorities for several biomedical applications. However, for some uses it is required that some of its properties be improved, namely in terms of thermo-mechanical and electrical performance. The incorporation of nanofillers is a common approach to attain this goal. The outstanding properties of carbon-based nanomaterials (CBN) have caused a surge in research works dealing with PLA/CBN composites. The available information is compiled and reviewed, focusing on PLA/CNT (carbon nanotubes) and PLA/GBM (graphene-based materials) composites. The production methods, and the effects of CBN loading on PLA properties, namely mechanical, thermal, electrical, and biological, are discussed.

“…Melting processing of nanocomposites is a versatile and efficient manufacturing process which can be rapidly applicable of industrial scale [ 37 ]. In the case of PLA-based nanocomposites, twin-screw extrusion is widely used since the mixing action is based on elongation flow [ 38 , 39 , 40 , 41 ]. In this work, we have explored the effects of the addition of GO and/or an IL on a polymeric matrix of PLA in order to optimize processing conditions and improve the properties of the PLA-based nanocomposites.…”

Extruded PLA Nanocomposites Modified by Graphene Oxide and Ionic Liquid

Polylactic acid (PLA)-based nanocomposites were prepared by twin-screw extrusion. Graphene oxide (GO) and an ionic liquid (IL) were used as additives separately and simultaneously. The characterization of the samples was carried out by means of Fourier transform infrared (FT-IR) and Raman spectroscopies, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). The viscoelastic behavior was determined using dynamic mechanical analysis (DMA) and rheological measurements. IL acted as internal lubricant increasing the mobility of PLA chains in the solid and rubbery states; however, the effect was less dominant when the composites were melted. When GO and IL were included, the viscosity of the nanocomposites at high temperatures presented a quasi-Newtonian behavior and, therefore, the processability of PLA was highly improved.

“…En el proceso de extrusión, además de la temperatura aportada por la camisa, se produce calentamiento por cizalla debido al giro del husillo, que va cortando el material y empujándolo contra las paredes del cilindro, produciendo altas fricciones. De esta manera, se está proporcionando al material la energía térmica de la camisa calefactada, más el calor debido a la fricción producida [253]- [255].…”

Con esta tesis dejo constancia, por escrito, desde hoy y para la prosperidad, del amor que siento por la ciencia, por el continuo crecimiento, por el enseñar y por el aprender, por el escuchar y por el ser escuchado, por la infinita creencia de que las cosas se pueden hacer mejor, de que se puede ser mejor y de que rodeado de la compañía correcta, todo es mejor.A mi director el Dr. José Sanes Molina, por ser un ejemplo del camino a seguir, habiendo dedicado una vida a la ciencia y la enseñanza. Gracias, por tu apoyo, tu sinceridad, tu constancia, tu buen hacer, cada uno de tus consejos y, sobre todo, cada una de las horas que has dedicado a ayudarme, en todo cuanto he necesitado. Gracias.Se ha observado que todos los líquidos iónicos y todos los nanofluidos utilizados reducen el coeficiente de fricción y el daño superficial cuando se utilizan como lubricantes externos sobre el polímero. Cuando se utilizan como lubricantes internos se observa que los líquidos iónicos apróticos que contienen el anión hexafluorofosfato no mejoran las propiedades tribológicas del polímero ni reducen el daño superficial. En cambio, tanto los líquidos iónicos apróticos que contienen el anión tetrafluoroborato, como el líquido iónico prótico y el nanofluido preparado a partir del líquido iónico prótico con óxido de zinc reducen notablemente el coeficiente de fricción de la matriz polimérica y el daño superficial.
