“…In contrast to amphiphilic bottlebrush copolymers, cellulose- grafted bottlebrush homopolymers have less hydrophilic moieties, promoting the formation of more advanced nanostructures by adding linear diblock copolymers with complementary nucleobases. Following the reported procedures, , linear diblock nucleobase-containing copolymers, polyethylene glycol- b -poly(4-((3(adenin-9-yl)propanoyl)oxy)butyl acrylate) (PEG 90 - b -PAAc 20 , PA ) and polyethylene glycol- b -poly(4-((3-(thymin-l-yl)propanoyl)oxy)butyl acrylate) (PEG 90 - b -PTAc 20 , PT ) were synthesized by using RAFT polymerization (Schemes S3 and S4 and Figures S9–S12).

Biological systems enable the efficient implementation of various functions by segregating responsive biomacromolecules or assemblies in disparate compartments, which is highly fascinating and desired by materials scientists. However, it is still challenging to elegantly modulate the responsive behaviors of mixed assemblies in synthetic polymeric systems owing to the lack of delicately responsive nanostructures. Herein, bioinspired complementary hydrogen bonding interactions of nucleobases are harnessed to achieve the programmable morphological transformations of mixed nanostructures from cellulose-grafted bottlebrush polymers. Both adenine-and thymine-containing cellulose-graf ted-polymers (Cell-g-PAAc and Cell-g-PTAc) were successfully synthesized by using reversible addition-fragmentation chain transfer (RAFT) polymerization. Furthermore, selfassembly of Cell-g-PAAc and Cell-g-PTAc produces well-defined spherical assemblies MA and MT without the discernible particle− particle interaction. In contrast, MA and MT undergo distinct morphological transformations with the introduction of linear diblock copolymers containing complementary nucleobases. By utilizing the novel properties of nanostructures from cellulose-grafted bottlebrush polymers, it is feasible to achieve the selective responsiveness of mixed nanostructures based on complementary hydrogen bonds of nucleobases. This work presents an efficient bioinspired strategy to elegantly modulate the responsive behaviors of mixed nanostructures, providing a cue for fabricating advanced synthetic stimuli-responsive materials.

“…Indeed, synthetic polymers can be produced from renewable biomass feedstocks, including natural biopolymers (such as cellulose, , hemicellulose, lignin, and so on) and molecular biomass (such as plant oils, − terpene, isosorbide, , and so on , ). Among them, renewable plant oil-based polymers have gained a lot of attention owing to the low costs and good renewability of plant oils. ,,,, Using plant oils as feedstocks, various biomass-based polymeric materials can be produced such as bioplastics, ,− thermoplastic elastomers, , coatings, , and adhesives. ,− The development of various plant oil-based polymeric materials not only decreases the consumption of limited fossil resources but also reduces the potential environmental pollution. In contrast to the common polymeric materials, fabricating high value-added frost-resistant and anti-icing siloxane-containing functional coatings from plant oils is of great significance.…”

Frost-resistant and anti-icing polymeric coatings are widely used for various industries for the extremely low temperatures that often appear in winter. Among different icephobic materials, nontoxic fluorinefree polysiloxanes with a low surface energy present tremendous potential to be utilized as passive icephobic coatings. However, conventional polysiloxanes from limited petroleum-based feedstocks potentially lead to serious resource crisis and environmental concerns. In this work, renewable plant oil-based polysiloxanes were prepared and exploited as passive frost-resistant and anti-icing materials. Renewable plant oil-based diene monomers were polymerized with 1,1,3,3-tetramethyldisiloxane through highly efficient hydrosilylation reactions to yield polysiloxanes. The optimized polysiloxane coating is efficient for the removal of the accumulated ice/frost by natural forces such as wind blowing and gravity. The icephobic coating has an ice adhesion strength as low as 84.8 kPa, presenting great potential for efficient anti-icing and frostresistant applications. The eminent passive anti-icing and frost resistance properties of the renewable plant oil-based polysiloxane coating could be attributed to its combination of low crystallinity and high chain mobility. The development of biomass-based polysiloxanes offers us an efficient route to access high value-added passive frost-resistant and anti-icing coatings.

“…Aqueous emulsion polymerization, − which usually consists of four components: water, a monomer, an initiator, and an emulsifier, is widely used in the laboratory and industrial preparation of polymer colloids with extensive interest in synthetic rubber, adhesives, paints, inks, coatings, electrophoretic displays, biological imaging, therapeutics, and optical probes . As a result of the centrosymmetric interfacial tension, polymer colloids produced by traditional emulsion polymerization are usually spherical particles with homogeneous chemical structure .…”

Monodisperse polymer hemispheres have been fabricated by seed emulsion polymerization of isobutyl methacrylate (iBMA) and acrylic acid (AA) using linear polystyrene (PSt) colloids as seeds, followed by the selected washing of alcohol/water. The morphological investigation performed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) indicates that polymer colloids are monodisperse round spheres and hemispheres before and after postpolymerization ethanol washing, respectively. Fluorescent microscopy demonstrates that the polymer colloids consist of hydrophobic cores and hydrophilic surfaces. Super-resolution imaging reveals that the thickness of the hydrophilic surface layer in polymer colloids is below 100 nm. The seed emulsion polymerization process was characterized by a fluorescent spectrophotometer and fluorescent microscopy based on the aggregation-induced emission (AIE) mechanism. The fluorescent intensity of AIE-active probes in polymer colloids increases as of emulsion polymerization proceeds. During seed emulsion polymerization, it is observed in the SEM images that polymer colloids are isotropic round spheres. Under a fluorescent microscope, however, one half of each polymer colloid shows much stronger fluorescence than the other half, which indicates that the microphase separation inside each polymer colloid occurs, causing anisotropic distribution of the chemical composition. It is of particular interest that the postpolymerization washing process determines the final shape of the polymer colloids. After the ethanol/water washing process to partially dissolve the hydrophilic polymers, the round polymer colloids are compressed into uniform anisotropic hemispheres as a result of the asymmetric distribution of the chemical composition in polymer colloids, which provides a promising alternative to prepare novel topological polymer colloids.
