Poly(ε-caprolactone) (PCL) is one of the promising polymers because it can be utilized as a substitute for petroleum-based polymers that are diffi cult to biodegrade in nature. PCL has non-toxic properties, high crystallinity, and biodegradable. Therefore, this polymer is widely used for medical purposes and environmentally friendly packaging. The purpose of this study was to compare the degree of polymerization, catalytic activity and thermal properties between PCL produced using bis(benzoylacetonato)zirconium(IV) catalyst (2a) with the PCL produced using other bis(β-diketonato)zirconium(IV) chloride catalyst (2b, 2c). In this research, ring opening polymerization (ROP) of ε-caprolactone (ε-CL) was performed by using complex 2a as a catalyst. The polymerization reaction lasts for 4 h at 100°C. The results of the research showed that ε-CL was successfully polymerized as proven in the results of its characterization. The molecular structure of the obtained PCL was analyzed by using FTIR, 1 H NMR, 13 C NMR, XRD, DSC, and TGA. The PCL produced in this study was a semicrystalline polymer. Meanwhile, a Mulliken charge of zirconium central atom in complex 2a-2c was also measured. In Mulliken charge analysis, the Mulliken charge of complex 2c has the highest Lewis acidity in comparison with complex 2a and 2b.

Since cellulose is the most common biopolymer in the world, there has been a lot of interest in its nanoscale version called nanocellulose due to the growing demand for sustainable products. To validate nanocellulose as a key component in the shift to a bio‐based economy, this review provides a thorough and critical assessment of the valorization of cellulose into nanocellulose, highlighting its unique properties, cutting‐edge extraction methods, surface modifications, and multiple applications. The study thoroughly compares nanocellulose with other natural and synthetic polymers, in contrast to earlier research, emphasizing the latter's inferior mechanical qualities, biocompatibility, and adaptability. In addition, we discuss recent developments in surface modification and extraction techniques that improve the performance of nanocellulose in high‐impact applications like medication administration, electronics, packaging, and environmental remediation. This analysis demonstrates the economic and sustainability potential of nanocellulose and suggests strategic options for future research by summarizing recent advances and identifying research gaps. Our study shows that turning cellulose into nanocellulose is valuable not just as a research project but also as a critical first step in creating long‐lasting materials to deal with the pressing issues of the twenty‐first century.
