Bottlebrush block copolymers (BBCPs) are a unique class of materials that contain backbone with densely grafted and chemically distinct polymeric side chains. The nonlinear architecture BBCPs provides numerous degrees freedom in their preparation, including control over key parameters such as grafting density, chain length, arrangement, overall molecular weight. This uniquely branched structure several important distinctions from linear counterparts, sterically induced conformations, rapid large self-assembled nanostructures, reduced or eliminated entanglement effects (assuming sufficient density the weight chains is below respective weight). These allow access to domain sizes, very assembly, ability preferentially add additives and/or precursors one domain, thereby enabling efficient fabrication wide range advanced devices. have been utilized create finely controlled well-ordered nanostructures for use applications, photonic crystals, drug delivery systems, energy conversion, storage devices, components surface coatings. To further deploy templates formation precise having thorough understanding synthesis, self-assembly, templating necessary. explore understand self-assembly subsequent applications BBCPs, this review emphasizes physics (including architectural, rheological, thermodynamic considerations) structure-property relationships between resulting nanostructures. Lastly, we provide an overview current research trends using storage, photonic, 3D printing, applications. We aim researchers fundamentals BBCP nanostructured continue development materials.

The synthesis of a fully biobased thermoplastic elastomer (TPE) is presented as an alternative to classical styrene/isoprene-derived TPEs. Limitations systems, e.g., the microstructure dienes or elaborate multistep addition pathways can be overcome by combination bifunctional initiation in scarcely used, moderately polar solvent methyl tert-butyl ether (MTBE) and using monomers β-farnesene nopadiene. derived from renewable sugar cane pine tree feedstocks. Excellent control carbanionic copolymerization confirmed situ NMR kinetics. study reveals that two-sided tapered ABA triblock copolymers are accessible one-step approach, capitalizing on difunctional initiator MTBE. material properties tuned broad range─highly elastic materials with elongation exceeding 1300% well tough Young's modulus 500 MPa were obtained. Small-angle Χ-ray scattering, temperature-modulated differential scanning calorimetry, rheology, dielectric spectroscopy employed relate phase state. They revealed local segregation accompanied respective glass temperatures, albeit absence long-range order.

Architecturally hindered crystallization of bottlebrush graft copolymers offers a reaction- and solvent-free pathway for creating injectable elastomers with tissue-mimetic softness. Currently, materials involve solvents chemical reactions, leading to uncontrolled swelling, leaching unreacted moieties, side reactions tissue. To address this issue, poly(ethylene glycol) (PEG) amorphous block crystallizable poly(lactic acid) (PLA) grafted chains (A-g-B) were synthesized, controlled length arranged along the backbone at spacing. The densely PEG brush is leveraged architecturally control both rate degree PLA grafts, offering tunability mechanical properties as function architecture time in single-component system covering broad range aggregation states comprising fluid-, paste-, elastomer-like behaviors modulus ranging from 1 50 kPa. PLA-g-PEG pastes are particularly interesting, they combine injectability time-controlled formation shape-persistent constant temperature. This molecular paste platform may advance reconstructive surgery, drug depots, tissue engineering.
