Effect of Commercial SiO₂ and SiO₂ from rice husk ash loading on biodegradation of Poly (lactic acid) and crosslinked Poly (lactic acid)

Effect of Biobased SiO2 on the Morphological, Thermal, Mechanical, Rheological, and Permeability Properties of PLLA/PEG/SiO2 Biocomposites

“…For example, PLA is a brittle polymer with a slow crystallization rate, poor toughness, average permeability properties, and moderate degradation [10]. Nevertheless, several modifications can be applied to enhance PLA's properties, including copolymerization [11,12], particle addition [13,14], polymer blending [15,16], and plasticization [13,[15][16][17]. The trend and development of environmentally friendly materials led to studies and research on new production techniques for biodegradable materials using PLA as a sugarcane-based thermoplastic [18], as well as lignin addition [19] for the production of materials with good mechanical properties, excellent thermostability, and biodegradability.…”

“…After milling rice, rice husks are often discarded, landfilled, or burned [45]. To solve this issue of a high amount of residue generation, research incorporating rice husk silica as reinforcement for agricultural fillerreinforced PLA composites has gained significant attention in the literature [14,40,[46][47][48][49][50][51]. Prapruddivongs et al [14] studied the biodegradation behavior of PLA.…”

Prapruddivongs et al [14] studied the biodegradation behavior of PLA. They crosslinked PLA filled with precipitated SiO 2 (commercial SiO 2 ) and SiO 2 from rice husk ash and found that SiO 2 incorporation has a direct effect on the composites' stability.…”
