“…Wu et al prepared the PLLA/MWNTs hybrids via a melt blending method. 22 The results demonstrated dramatic enhancement in thermal properties of PLLA. Shieh et al prepared films of the PLLA/MWNTs-g-PLLA nanocomposites by a solution casting method to investigate the effects of the MWNTs-g-PLLA on the nonisothermal and isothermal melt crystallizations of the PLLA matrix.…”

Biodegradable poly(L-lactide) (PLLA)/multiwalled carbon nanotubes (MWNTs) nanocomposites were prepared via solution blending using two kinds of MWNTs, i.e., pristine multiwalled carbon nanotubes (p-MWNTs) and carboxyl-functionalized multiwalled carbon nanotubes (f-MWNTs). Various techniques were used to investigate the functionalization of MWNTs on the morphology, crystallization, and hydrolytic degradation of PLLA in the nanocomposites. Both MWNTs show fine dispersion in the PLLA matrix; however, the dispersion of f-MWNTs is better than that of p-MWNTs. The incorporation of MWNTs accelerates the crystallization of PLLA in the nanocomposites due to the heterogeneous nucleation effect; furthermore, the crystallization rate of PLLA is faster in the PLLA/f-MWNTs nanocomposite than in the PLLA/p-MWNTs nanocomposite. The exciting aspect of this research is that the hydrolytic degradation of PLLA is enhanced after nanocomposites preparation.

“…Therefore, polymer blending and preparation of nanocomposites have often been employed to modify the physical properties of PLA in order to extend the practical applications [7][8][9][10][11]. Various nano-reinforcement fillers, such as layered silicate clay [12], carbon nanotubes [13], and layered double hydroxide [14], are being developed and extensively studied in various polymer matrices.…”

Abstract:The superlative mechanical properties of graphene-based materials make them the ideal filler materials for polymer composites reinforcement. Two types of graphene-based materials, graphene nanoplatelets (xGnP) and reduced graphene oxide (rGO), were used as nanofiller in poly(lactic acid) (PLA) polymer matrix, as well as plasticized PLA. The addition of rGO into PLA or plasticized PLA substantially enhanced the tensile strength without deteriorating elasticity, compared to xGnP nanocomposites. In addition, the investigation of the thermal properties has found that the presence of rGO in the system is very beneficial for improving thermal stability of the PLA or plasticized PLA. Scanning electron microscope (SEM) images of the rGO nanocomposites display homogenous and good uniformity morphology. Transmission electron microscopy (TEM) images revealed that the rGO remained intact as graphene sheet layers and were dispersed OPEN ACCESS Polymers 2014, 6 2233 well into the polymer matrix, and it was confirmed by X-ray diffraction (XRD) results, which shows no graphitic peak in the XRD pattern.
