Modification of low‐molecular polylactic acid by CaF2 nanoparticles: A new approach to change its material properties

Abstract: Due to environmental problems and the increasing waste of resources, sustainable biodegradable plastics has become a great topic worldwide. In this communique, we present a simple low‐cost synthesis to improve one of these typically used materials, PLA (polylactic acid). CaF2 nanoparticles synthesized according the fluorolytic sol–gel synthesis in lactic acid give access to fine tune the material characteristics of LMPLA (low‐molecular polylactic acid) due to a simply to apply polycondensation reaction of lact… Show more

“…A combination of CaF 2 and MgF 2 was also synthesized in ethylene glycol. In addition, another formulation of CaF 2 sol was synthesized in lactic acid (Mahn and Kemnitz 2019). A 0.1 M NaF solution was also prepared for impregnation into wood specimens for comparison.…”

“…Nano metal fluorides are increasingly accessible since the fluorolytic sol gel synthesis was reported in 2003 (Kemnitz et al 2003). Based on this synthetic accessibility, nano metal fluorides have been applied to anti-reflective coatings, bio-medicine and bio-plastics (Sun and Chow 2008;Krahl et al 2016;Mahn and Kemnitz 2019). The homodispersed nanoparticles have been characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and dynamic light scattering (DLS) (Usmani et al 2018).…”

“…Recently, biodegradable and/or biobased thermoplastics have been widely used as alternative materials for replacing the non-biodegradable polymers derived from the fossil fuel-based materials in an effort to alleviate the solid waste accumulated in the environment and landfills as well as the use of nonrenewable petroleum resources. [1][2][3][4] Poly(lactic acid) (PLA), a very versatile aliphatic polyester, has currently emerged among the most important biodegradable and biobased polymers with several attractive properties, such as biocompatibility, commercial availability, and relatively high strength and stiffness. [1][2][3][4][5][6][7][8] PLA can be produced from monomers derived from agricultural renewable and sustainable resources, such as cornstarch, sugarcane, and sugar beet.…”

“…22). In the simplest case, the latter goal is already achieved by addition of a certain fraction of a more hydrophilic acrylate bearing hydroxyl groups like HEMA (2-hydroxyethyl methacrylate), HBMA (2-hydroxybutyl methacrylate) or bis-GMA (bisphenol A-glycidyl methacrylate) [49,114,115].…”
