Via a batch process in an autoclave, the foam processing of neat polylactide (PLA) and two different types of PLA-based nanocomposites (PLACNs) has been conducted using supercritical carbon dioxide (CO2) as a foaming agent.
Here, we present the simple AM processing of poly(lactide-block-ethylene glycol-block-lactide) (PLA-PEG-PLA) triblock copolymers via melt electrospinning writing (MEW).
This review discusses the opportunities for PLA blends in the biomedical arena, including the overview of blending and postblend processing techniques and the applications of PLA blends currently in use and under development.
The ease of melt processing has led to the production of PLA fibers, which are increasingly accepted in a wide variety of textiles from dresses to sportswear, furnishing to drapes, and soft nonwoven baby wipes to tough landscape textiles.
Specifically, because of PLA's competitive material and processing costs, and its comparable mechanical properties, PLA foams could potentially replace polystyrene (PS) foam products in a wide array of applications such as packaging, cushioning, construction, thermal and sound insulation, and plastic utensils.
BE significantly increased the cold crystallization ability of PLA, which was valuable for practical processing and performance.
It was found from DSC scans that Tg of PLA drastically decreased with introducing MOPEO-PLA, indicating that MOPEO-PLA miscible with PLA.
Since in typical method the porogens are dispersed in the solution and flow with the polymers during the casting and the crystallinity behavior of PLA chains in the limited space cannot be tracked, in this work the processing is modified by diffusing the PLA solution into a steady salt stack.
Multiple processing by means of successive injection cycles was used to simulate the thermo-mechanical degradation effects on the oligomeric distribution of PLA under mechanical recycling.
