Poly(lactic acid) (PLA) filled with wood flour (WF) is more susceptible to hydrolysis compared to pure PLA. This work shows that the hydrolysis reactions leading to chain scission can be hindered by using 2 wt% of bis(2,6-diisopropylphenyl)carbodiimide (ZIKA). It was found that the addition of ZIKA supports the crosslinking of PLA/WF composite. The crosslinking slightly hindered the annealing efficiency of wood flour and increased the stiffness of biocomposites. The thermal stability of biocomposites containing ZIKA was slightly improved. The relevance of the antihydrolysis effect of ZIKA during melt processing of biocomposites was correlated with the rheological and molar mass properties. The hydrolytic stability of biocomposites was determined under buffer solution conditions at accelerated temperature 80 °C and pH of 7. The determined lower depolymerisation and hydrolysis rates of PLA/WF-ZIKA composites indicate that the service lifespan of biocomposites can be prolonged by the addition of ZIKA additive.

与纯PLA相比，填充有木粉（WF）的聚乳酸（PLA）更易于水解。这项工作表明，通过使用2 wt％的双（2,6-二异丙基苯基）碳二亚胺（ZIKA），可以阻止导致断链的水解反应。发现添加ZIKA支持PLA / WF复合材料的交联。交联稍微阻碍了木粉的退火效率并增加了生物复合材料的刚度。含有ZIKA的生物复合材料的热稳定性略有提高。ZIKA在生物复合材料熔融加工过程中抗水解作用的相关性与流变学和摩尔质量特性相关。在加速温度80°C和pH值为7的缓冲溶液条件下测定了生物复合材料的水解稳定性。
