Summary: This research describes the synthesis of hollow capsules through the polymerization-induced interfacial self-assembly (PIISA) approach. The method involves using a hydrophilic polymer as a macro-CTA, toluene droplets in water as templates, and MMA as a monomer. As the PMMA block length increases, the formed BCP chains migrate to the liquid-liquid interface, reducing the interfacial tension.

Summary: Interfacial polymerization is used to fabricate functional nanofilms for various applications by assembling polymer nanofilms at the water-oil interface in the presence of surfactants. Through in situ visualization and computational simulations, this study reveals the critical role of Marangoni instability induced by surfactants in structurally regulating nanofilms. Despite different instability-triggering mechanisms, the delicate control of surfactants enables the fabrication of defect-free nanofilms with ultra-permselectivity.

Summary: The field of sustainable polymers from renewable feedstocks is emerging after petroleum-based polymers dominated for decades. Amide-containing polymers have diverse properties depending on the type of amide, its density, and other molecular structural parameters. Incorporating amide groups into sustainable polymers through monomer design is a proven industrial strategy, and bio-based monomers are crucial in bridging the gap between renewable sources and amide-containing sustainable polymers (AmSPs). This feature article conceptualizes the monomer-design philosophy behind most AmSPs and discusses di-functional monomers for step-growth polymerization, cyclic monomers for ring-opening polymerization, and amide-containing monomers for chain-growth polymerization. A perspective on monomer design and performance enhancement of AmSPs is also provided.

Summary: A series of hardeners were prepared by reacting elemental sulfur with renewable 10-undecenoic acid, which were further employed for curing diglycidyl ether of bisphenol-A (DGEBA). The resulting solvent- and catalyst-free dynamically cross-linked epoxy networks exhibited high tensile strength and toughness, which were well maintained during repetitive thermal processing due to exchanges of the S-S bonds and beta-hydroxyl ester moieties. The toughened epoxy resins also showed a high adhesion strength of up to 31 MPa for steel plates. Additionally, the joined plates could be easily separated without any residual resins by immersing in a methanol solution of Na2S or hexylamine.

Summary: Designing sustainable phenolic polymers with tunable mechanical properties, intrinsic degradability, and recyclability is crucial in polymer science. Traditional phenolic resins are generally considered non-degradable or recyclable. In this study, we report the synthesis of linear and network structured phenolic polymers using an easy polycondenstation method. These polymers exhibit excellent mechanical strength and are susceptible to degradation in oxidative conditions. These findings highlight the potential of biobased sustainable phenolic polymers as an alternative to traditional phenol-formaldehyde resins.

Summary: In the past decades, click chemistries, including thiol chemistries, have been widely used in synthesizing well-defined polymers. This research proposes a click-declick strategy for the synthesis of cleavable polymers based on the oxidation of heteroaromatic thioethers and substitution reactions with thiols. Proof-of-concept experiments demonstrate the synthesis of block copolymers and star-like polymers through thiol-phenylsulfone substitution reactions, resulting in the production of heteroaromatic thioethers at the junction points of the polymer chains. The thioethers can be oxidized to heteroaromatic sulfoxides or sulfones and cleaved through base-catalyzed nucleophilic substitution reactions with thiols.

Summary: Polymer brushes are densely grafted polymer chains on surfaces or interfaces. They can self-assemble or coassemble with block copolymers to form surface nanostructures with different morphologies. In this study, polymer brushes and surface nanostructures were synthesized on tannic acid (TA) coatings. The brushes were anchored onto TA coatings through electrostatic interaction, and surface nanostructures were formed. The density of the polymer chains and the concentration of the block copolymers affected the formation of the nanostructures. These nanostructures could be removed from the surfaces in a sodium chloride solution.

Summary: In this paper, sulfur chain-modified epoxy networks (SxEyUz) were designed through catalyst-free tri-component polymerization of elemental sulfur with glycidyl ethers of bio-sourced eugenol (EGE) and 10-undecenol (UGE) using inverse vulcanization. The biogenic allyl protons on EGE were found to be crucial for the dual-mechanism cross-linking system. The intermediates from the tri-component polymerization exhibited flowable, storable, and post-curable properties. Reprocessable epoxy polymers with high tensile strength were obtained, surpassing most reported bio-based polymers. Furthermore, the carbon fiber (CF) composites fabricated in the SxEyUz matrix can be easily digested in a methanol solution of Na(2)S and neat hexylamine for CF recycling.

Summary: Surfactant-free reversible addition-fragmentation transfer (RAFT)-mediated emulsion polymerization has been used to synthesize latex particles. In this study, RAFT emulsion polymerization of methyl methacrylate (MMA) mediated by protonated poly(2-(dimethylamino)ethyl methacrylate) (H+-PDMAEMA) macromolecular chain transfer agent (macro-CTA) was investigated. The nucleation time and rate of emulsion polymerization were found to be dependent on the chain length of H+-PDMAEMA-CTA and the molar ratio of free radical initiator/macro-CTA. The size and size distribution of the latex particles could be controlled by adjusting the macro-CTA chain length and MMA/macro-CTA molar ratio.
