En 中文
Poly(lactic acid) (PLA) is considered a bioplastic, a stable and recyclable polymer obtained from natural sources such as corn. This is why it is an eco-friendly bio-polymer as an alternative to petroleum-based plastics. Its flexibility and environmental advantages have led to extensive use across a range of applications. Thus, PLA polymer is sensitive to UV light, which causes degradation, presenting both challenges and opportunities, depending on the needed application. In outdoor usage, photodegradation of PLA can cause polymer chain scission, structural deterioration, and a decrease in material performance. This could raise serious issues for applications requiring long-term stability. Hence, controlled photodegradation can be quite useful for applications where faster degradation rates are desirable. Recent advancements have focused on enhancing the photostability and photodegradability of PLA through the incorporation of various nanoparticle materials. These molecules can protect the polymer from UV irradiation by absorbing, reflecting, emitting, or scattering the UV light. On the other hand, these molecules could improve photodegradation through the formation of radicals that attack the polymer chains. By re-engineering PLA with targeted NPs, its stability can be tailored to suit specific applications, whether to improve durability for outdoor use or to enable rapid degradation. This method gives promising approaches for researchers to develop PLA-based bio-polymer materials with enhanced performance under UV exposure.
