Polylactic Acid Composites and Composite Foams Based on Natural Fibers

Study on the biodegradability of modified starch/polylactic acid (PLA) composite materials

“…Water contact angle tests showed that the lysine-modied PLLA-PEG copolymer has good water solubility, and its water contact angle is 67 , while the pure PLLA and PLLA-PEG copolymers have water contact angles of 114 and 82 . 14 It has therefore been proven that the addition of hydrophilic lysine improves the hydrophilicity of the PLLA-PEG copolymer and is a good bioengineering material.…”

“…Materials widely used in the elds of surgical sutures, orthopedic xation materials, in vivo implant materials, and medicinal control systems, are globally recognized as the most promising biomedical materials this century. 3 PLA is produced using lactic acid as a raw material. Most traditional fermentation processes use starchy raw materials to produce lactic acid.…”

Effect of Starch Type and Pre-Treatment on the Properties of Gelatin–Starch Foams Produced by Mechanical Foaming

“…Natural fibers and nanocellulose have emerged as promising materials to incorporate into foam formulations. Biocomposite foam materials containing natural fibers, such as kenaf, hemp and flax, have improved mechanical strength, modulus and thermal stability [ 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. Nanocellulose, on the other hand, is a valuable nanofiller for biopolymer foam composites, offering potential improvements in foam properties and cost reduction [ 19 , 20 ].…”

Renewed interest in biopolymer composites: incorporation of renewable, plant-sourced fibers

“…Currently, two important ways in which composites are becoming more sustainable are composite material recycling, and the use of renewable components. 7–9 This review highlights advances towards more renewable composite materials and the recyclability of composite materials. 10,11…”
