Insights Into the Kinetics and Chain Extension in the Synthesis of Cholesterol-Terminated Poly(Tert-Butyl Acrylate) via Controlled Radical Polymerization Gina Tavares, Patrícia Alves, João Rodrigues, Pedro N. Simões Journal of Polymer Science, 2025 Cholesterol‐terminated poly(acrylic acid) was prepared through a simple two‐step method, consisting of the reversible‐deactivation radical polymerization of tert‐butyl acrylate with a cholesterol‐based initiator and acidic hydrolysis of the tert‐butyl group. The Cu(0)/Cu(II) catalytic system allowed the controlled polymerization of tert‐butyl acrylate with narrow dispersity in less than an hour. Kinetic studies revealed that the initial catalyst ratio influences the polymerization time by means of an induction period that increases with the [Cu(II)]0/[Cu(0)]0 ratio. The effect of nitrogen purge and freeze‐pump‐thaw cycles was assessed, and both were found to be equally effective in the system deoxygenation. The synthesized polymers exhibited a high degree of chain‐end fidelity, as evidenced by the results of chain extension experiments. This makes the system interesting for the formation of block copolymers with cholesterol‐termination, broadening its range of applicability.
PLLA-PEG/mPEG Copolymer with Improved Hydrophilicity, Crystallinity, and Biocompatibility: An In-Depth Study on the Crystallization Kinetics Ruixian Lian, Dong Zhou, Lan Xiao, João Rodrigues, Ruilong Sheng, et al. ACS Applied Materials and Interfaces, 2025 Poly(lactic acid) (PLA) possesses excellent biocompatibility and biodegradability for the construction of biomaterials. However, its limited crystallinity largely restricts practical application. In this study, four poly(l-lactic acid) (PLLA) copolymers were synthesized by incorporating two different molecular weights of PEG/mPEG (1K and 2K) chains with l-lactide via ring-opening polymerization (ROP). The impact of PEG/mPEG chains on the hydrophilicity and mechanical properties of the resulting copolymers, their crystallization kinetics, and activation energy was also examined. The results demonstrate that introducing PEG/mPEG chains could significantly improve the hydrophilicity, crystallinity, and crystallization rate and reduce the maximum crystallization temperature of the copolymer materials. Among the PLLA copolymers, PLLA-mPEG (2K) exhibits the most remarkable improvements in polymer crystallinity, crystallization rate, and reduction of the maximum crystallization temperature. The advancements in copolymer material properties were anticipated to significantly expand the potential applications for PLLA-based polymer materials, which also greatly improved the applicability as sustainable and controllable biopolymer materials.
Bioinspired hybrid DNA/dendrimer-based films with supramolecular chirality Rita Castro, Pedro L. Granja, João Rodrigues, Ana Paula Pêgo, Helena Tomás Journal of Materials Chemistry B, 2025 Hybrid DNA/dendrimer films were obtained by heating dsDNA above its Tm and, while in the denatured state, mixing it with dendrimers, followed by controlled cooling. Films are stable, cytocompatible and show evidence of supramolecular chirality.
