Kobunshi Kagaku, 1958 グリセリン浴およびエチレングリコール浴で紡糸したアクリル繊維未延伸糸を延伸し, 延伸による強伸度, 密度, X線による配向度および側間規則性, 顕微鏡による断面形状などの変化を調べた。1) エチレングリコール浴で紡糸した未延伸糸の密度は著しく小さい。延伸によってその密度は増加するが, 4倍以上の延伸ではその増加の程度が少ない。グリセリン浴で紡糸した未延伸糸の密度は大きく, 延伸による変化はほとんどない。2) 延伸によって強度および初期弾性率は大きくなるが, 同一延伸倍率ではグリセリン浴で紡糸した糸を用いた場合の方がこれらの値は大きく, X線的配向度も同じような傾向を示している.このような機械的性質に対しては分子の配向が支配的な影響をもっている. 3) 延伸によって配向度および側間規則性は良くなるが,

Advanced Materials, EarlyView.Polymer electrolytes (PEs) are often indiscriminately grouped as “solid polymer electrolytes (SPEs)”, despite fundamental differences in their ion‐transport mechanisms. This Perspective establishes a mechanism‐based framework that distinguishes gel, quasi‐solid, and all‐solid polymer electrolytes based on their dominant ion‐transport pathways.

Self-Emulsion Polymerization of Baylis–Hillman-Derived α-Hydroxymethyl-Substituted Acrylates
, 2015 Amphiphilic alkyl α-hydroxymethyl acrylates can be polymerized via self-emulsion polymerization (i.e., without surfactants) under conventional radical and reversible addition-fragmentation chain transfer polymerization conditions.

Advanced Materials, EarlyView.Inspired by the octopus and the golden wheel spider, soft robots with liquid crystal elastomer arc fibers as appendages are fabricated to transcend surface constraints through an elevated center of mass and minimal contact footprints. By leveraging curvature‐encoded deformation‐recovery cycles, these robots exhibit contractile, torsional, and flexural ...

Cell Adhesion by Design: Engineering Tissue Culture Scaffolds With Adhesion Cues
Advanced Materials Interfaces, EarlyView.ABSTRACT In scaffold‐based tissue engineering, the matrix should provide adequate adhesion cues for cell attachment, spreading, and function. Given the multitude of adhesion receptors and the diversity of scaffolds, there are many approaches to render scaffolds adhesive, even though they are not all equivalent.

3D Printing of Stretchable, Compressible and Conductive Porous Polyurethane for Soft Robotics
Advanced Materials Technologies, EarlyView.A 3D‐printable porous dopamine‐polyurethane acrylate elastomer results in conductive, stretchable, and compressible structures that can be metallized in situ through catechol‐mediated silver reduction. The resulting material function as both compliant soft robot with a and strain sensors without complex assemblies, enabling fully 3D‐printed soft ...
