A bottlebrush polymer consists of a long linear backbone densely grafted with many relatively short side chains. widely accepted view is that strong steric repulsion among the highly overlapped chains prestrains backbone, resulting in low extensibility. However, we recently discovered melt polymers incompatible and collapses to reduce interfacial free energy, regardless Despite this discovery, molecular structure these so-called "foldable" their assemblies remains poorly understood. Here, present deterministic relationships architecture, mesoscopic conformation, macroscopic properties foldable polymers. combination scaling theory experiments reveals as chain grafting density decreases, diameter increases, whereas end-to-end distance decreases. These behaviors contradict existing understanding polymers, which assumes are compatible. Since store lengths can be released upon large deformations, they offer way decouple intrinsic stiffness-extensibility trade-off single-network elastomers. findings provide foundational insights into using building blocks for designing soft (bio)materials.

Entanglement significantly enhances the mechanical performance and functionality of both natural synthetic materials. However, developing straightforward, versatile strategies for creating high-performance entangled polymer materials remains a challenge. Here, co-initiating-system dual-mechanism strategy is designed fabricating printable multinetworks. This thermal-light dual-initiation process benefits synthesis high-molecular-weight polymers promotes rapid formation multinetworks within hydrogels. The resulting long chains enable hydrogels with higher performance, lower stress relaxation, activation energy compared to short chain-contained samples. Such method proves more effective than traditional self-thickening strengthening techniques enhancing hydrogel entanglements also compatible additive manufacturing, enabling design complex 2D webs adaptive capable detecting sensing applications. work provides an designing materials, which are set impact numerous fields, from advanced material science beyond.
