Improving tensile strength and impact toughness of plasticized poly

Abstract Poly (lactic acid) (PLA) biocomposites are usually plasticized to overcome the problem of poor ductility, which decreases the valuable tensile strength. In this study, novel nanofibrillated cellulose (NFC) was extracted to enhance the acetyl tributyl citrate (ATBC) plasticized PLA biocomposites.

On the contrary, an increase in concentration of lipophilic plasticizers (ATBC and VES) from 10% w/w to 30 % w/w led to a reduction in degradation of THC-HG (Fig. 6b). However, in the case of the PEO-VES system, the reduction was seen only until 20 % w/w concentration with no significant improvement at 30% w/w.

When ISB and ATBC content increases in plasticizer systems, the FWHM values decrease; this indicates the good compatibility of ISB and ATBC with PVC. From the frequency dependence of the T¦Á, the values of activation energy for the plasticized samples are calculated ( Table 3 ).

Those blends plasticized with ATBC showed higher flexibility and thermal stability than those with PEG. The best properties for the intended use in films manufacturing were found for the PLA¨CPHB¨CATBC formulation, with moderate elongation at break, slightly amber color but still mostly transparent, reduced surface water absorption and a considerable improvement in oxygen barrier.

Combined Effects from Dual Incorporation of ATBC as Plasticizer

The good solubility of PLA in the citrate plasticizers, owing to the polar interactions between the ester groups of PLA and the plasticizer , makes the acetyl tri-n-butyl citrate (ATBC), which is also biodegradable and non-toxic compound, a successful and common alternative to be added to PLA [1,4,13].

Tributyl citrate (TBC) and acetyl tributyl citrate (ATBC), as phthalate alternative plasticizers, show limited application due to low migration resistance, high volatilization rate and intense respiratory irritation. Meanwhile, the developed pure citrates, such as butyryl trihexyl citrate (BTHC) due to its high cost, and triisooctyl citrate (TOC) and acetyl triisooctyl citrate (ATOC) due to

The group using ATBC as the plasticizer showed the most stability, coupled with a low change rate of G¡ä and G¡å. When the polymer powder and plasticizer of soft polymer material are mixed, the polymer dissolves in the plasticizer and polymer chain entanglement occurs, finally forming a gel.

Consequently, neither the plasticizer nor the nucleating agent has a negative effect on the processing stability or rheological characteristics of the studied blends. 4.2 Mechanical properties
