“…Chloroform is the most used solvent to prepare PLA/CNT composites [ 138 , 139 , 140 , 141 , 142 , 143 ]. Despite, some authors obtain good results with THF [ 88 , 144 ], and dichloromethane [ 145 , 146 ]. McCullen et al [ 147 ] conclude that a combination of chloroform and DMF is beneficial.…”

“…However, this increase only occurs around PLA transition temperature (60–65 °C). At ambient temperature, the best result is an increase of 67% with incorporation of 3 wt % A-SWCNT-Si (acid treated and grafted with 3-isocyanatoporpyl triethoxysilane) in PLA by sonication, followed by drying and compression molding at 190 °C [ 144 ]. The maximum increase in σ max is of 129 wt %, obtained with incorporation of 0.4 wt % GNP-M in PLA by sonication and film casting by doctor blading [ 135 ].…”

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

et al. 2017

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.

“…The biodegradable polymers poly(lactic acid) (PLA), poly(butylene succinate) (PBS) and microcrystalline cellulose (MCC) have recently become widely used in the biomedical and packaging applications, due to their biocompatibility and environmentally friendly characteristics [1][2][3][4][5][6][7][8]. While PLA and PBS are synthetic aliphatic polyesters, MCC is a cellulose that is typically extracted from plant fibers and other similar cellulosic wastes by acid hydrolysis to remove the amorphous regions [2,[9][10][11].…”

“…With these advantages and an effective process for its mass production, PLA has received consideration attention for preparing bioplastics to replace commodity plastics, particularly in disposable packaging applications, and for use as one of the components in biodegradable blends and composites. However, PLA possesses some drawbacks, such as an inherent brittleness, low impact strength, poor melt strength, narrow processing window and low thermal stability [5,7,8,[18][19][20][21]. Its thermal degradation upon thermal processing is predominantly caused by the random main-chain scission and unzipping depolymerization reactions that are accompanied by a significantly increased level of carboxyl and hydroxyl end groups [19].…”

Biodegradable Plastics Prepared from Poly(lactic acid), Poly(butylene succinate) and Microcrystalline Cellulose Extracted from Waste-Cotton Fabric with a Chain Extender

This study aimed to improve the brittleness and thermal stability of poly(lactic acid) (PLA) by inclusion of poly(butylene succinate) (PBS) and microcrystalline cellulose (MCC). Of the three PLA/PBS blends (10, 30 and 50 wt% PBS) evaluated, the 70/30 wt% blend exhibited the highest impact strength and elongation at break, but a lower thermal stability compared to that of the pure PLA. Scanning electron microscopy analysis confirmed the better compatibility of this 70/30 PLA/PBS blend. This blend was further filled with MCC. Based on thermogravimetric analysis, the thermal stability of the 70/30 PLA/PBS blend was improved by the addition of MCC [optimal at five parts by weight per hundred (phr)] and further still by the addition of the chain extender, Joncryl TM , at 0.5 phr. The 70/30/5/0.5 PLA/PBS/MCC/Joncryl TM composite exhibited the highest impact strength, while the elongation at break was acceptable.

“…Chiu et al [ 29 ] studied the effects on functionalized, single-walled carbon nanotubes (SW-CNTs) on the properties of PLA. Their presence resulted in a significant increase of the dimensional stability, the storage modulus, the glass transition temperature, and a reduction of surface resistivity.…”

Injection Molding and Mechanical Properties of Bio-Based Polymer Nanocomposites

et al. 2018

The use of biodegradable/bio-based polymers is of great importance in addressing several issues related to environmental protection, public health, and new, stricter legislation. Yet some applications require improved properties (such as barrier or mechanical properties), suggesting the use of nanosized fillers in order to obtain bio-based polymer nanocomposites. In this work, bionanocomposites based on two different biodegradable polymers (coming from the Bioflex and MaterBi families) and two different nanosized fillers (organo-modified clay and hydrophobic-coated precipitated calcium carbonate) were prepared and compared with traditional nanocomposites with high-density polyethylene (HDPE) as matrix. In particular, the injection molding processability, as well as the mechanical and rheological properties of the so-obtained bionanocomposites were investigated. It was found that the processability of the two biodegradable polymers and the related nanocomposites can be compared to that of the HDPE-based systems and that, in general, the bio-based systems can be taken into account as suitable alternatives.
