Summary: Surface-initiated polymerization reactions offer a powerful tool to generate chain-end-tethered polymer brushes. This report introduces a synthetic strategy for producing structurally well-defined hydrocarbon polymer brushes of controlled molecular weights, which can be further modified to create more complex surface-attached polymer architectures. By using an alkylboronic acid pinacol ester initiator, controlled, unidirectional chain growth is achieved, allowing for the generation of micropatterned polymethylene brush films. Furthermore, conversion of the boronic ester chain-end functionalities to hydroxyl groups enables selective chain-end modification and access to various surface-anchored block copolymer architectures.

Summary: A method is reported to fabricate controllable superhydrophobic surfaces by directly transforming fluorinated monomer micro-droplets into hydrophobic polymer particles in water. The as-prepared surfaces show superior superhydrophobicity and great stability in extreme conditions, and the hydrophobicity can be manipulated by adjusting emulsion droplet number density and reaction time. This study provides an equipment-free method to fabricate controllable superhydrophobic surfaces with potential applications in engineering and industrial fields.

Summary: Surface-initiated reversible addition-fragmentation chain transfer polymerization using oxygen (O2-SI-RAFT) was used to impart chiral properties to substrates. Chiral monomers were synthesized and grown onto titanium and glass substrates, forming polymer brushes. The presence of polymer brushes was confirmed through various analyses, including ellipsometry, water contact angles, X-ray photoelectron spectroscopy, and atomic force microscopy. By polymerizing block copolymer brushes through chain extension, the chirality of the polymer brushes grown on glass substrate was confirmed using circular dichroism spectroscopy.

Summary: Since the past few decades, surface-initiated photopolymerization techniques have gained increasing interest. Coupling of photoinitiators to surfaces and particles has become an important research topic in material and surface sciences. Covalent coupling of photoinitiators and subsequent photopolymerizations provide a wide range of surface properties.

Summary: The report presents a facile and generalized approach to modify solid surfaces with polymer brushes under ambient conditions using filter paper-assisted surface-initiated Cu-0-mediated controlled radical polymerization (PSI-CuCRP). The method allows for selective surface grafting with good control over polymer brush quality, demonstrating the versatility by grafting different polymer brushes with high chain-end functionality. The combination of photolithography and paper cutting enables the preparation of arbitrary three-dimensional patterned polymer brushes on the surface.

Summary: This study reports a facile method of gallium-based liquid metal (GLM) nanodroplets mediated surface-initiated atom transfer radical polymerization (SI-ATRP) for preparing polymer brushes on GLM surfaces. The feasibility of GLM surface modified SI-ATRP is confirmed by UV-vis spectra, which also indicates that the thickness and density of polymer brushes are crucial for successful ATRP on GLM nanodroplets surfaces. Polymer brushes modified GLM nanodroplets show potential applications such as friction reduction and oil-water emulsion separation.

Summary: This study reports the development and use of bench-stable NHC adsorbates for the direct formation of NHC films on gold surfaces under ambient conditions. The generated NHC SAMs were fully characterized and compared to analogous SAMs generated from a different adsorbate. Furthermore, the potential utility of these NHC films as surface-initiated polymerization platforms was demonstrated.

Summary: Polymer brushes can be produced by surface-initiated polymerization using initiators or chain transfer agents. This manuscript presents an alternative method using non-covalent host-guest interactions to immobilize initiators for atom transfer radical polymerization. These non-covalent initiators can generate supramolecular polymer brushes with film thicknesses over 100 nm.

Summary: Surface-initiated reversible addition-fragmentation chain transfer polymerization using oxygen (O-2-SI-RAFT) allows material-independent surface coating on various substrates in the presence of air. The excellent growth of polymer brushes, including the highest reported growth on Ti/TiO2 substrates, was characterized. Additionally, large surfaces can be coated with polymer brushes by O-2-SI-RAFT, demonstrating versatility and efficiency.

Summary: Surface functionalization using covalently grafted molecules has successfully enhanced the interfacial integrity of epoxy-based composites. However, there are limitations in applying this strategy to composite resins based on chain-growth polymerization mechanisms. This study introduces a concept based on short, surface-grown polymers to systematically enhance and tailor the interfacial mechanical properties of these composites, providing practical guidance for optimizing the interface and expanding their applications.

Summary: Through Monte Carlo simulation, this study revealed that there are differences in molecular weight, dispersity, and molecular weight distribution between bulk-initiated polymers and surface-initiated polymers, indicating the invalidity of the equivalent assumption. The heterogeneous distribution of reactants in the system was identified as the main factor contributing to these differences.

Summary: Hydrogels are important wound-healing materials that are usually synthesized using a radical polymerization approach. However, the development of initiator-free hydrogels has gained attention due to their excellent cytocompatibility and ease of scale-up. In this study, initiator-free zwitterionic hydrogels were developed using a photopolymerization process under cytocompatible conditions. These hydrogels exhibited a wide range of mechanical characteristics, resist nonspecific protein adsorption, and showed sustained release of proteins and small molecules. Additionally, these self-initiated hydrogels significantly reduced inflammatory macrophage activation in vitro.
