Slide-ring materials using topological supramolecular architecture

K Ito - Current Opinion in Solid State and Materials Science, 2010 - Elsevier
We have recently developed a novel type of gel called slide-ring gel or topological gel by
using the supramolecular architecture with topological characteristics. In this gel, polymer …

The polyrotaxane gel: A topological gel by figure‐of‐eight cross‐links

Y Okumura, K Ito - Advanced materials, 2001 - Wiley Online Library
Supramolecules with topological characteristicshave attracted great interest both
experimentally and theoretically. A new kind of gel has been obtained by chemically cross‐linking …

Tough hydrogels with rapid self-reinforcement

…, T Noritomi, H Yokoyama, K Mayumi, K Ito - Science, 2021 - science.org
Most tough hydrogels are reinforced by introducing sacrificial structures that can dissipate
input energy. However, because the sacrificial damage cannot rapidly recover, the toughness …

Recent advances in the preparation of cyclodextrin-based polyrotaxanes and their applications to soft materials

J Araki, K Ito - Soft Matter, 2007 - pubs.rsc.org
The present review article deals with recent novel studies on the preparation and application
of polyrotaxanes comprised of cyclodextrins (CDs) and various linear polymers, especially …

From topological gels to slide‐ring materials

Y Noda, Y Hayashi, K Ito - Journal of Applied Polymer Science, 2014 - Wiley Online Library
A novel type of gel, called a topological gel, has been recently developed with a supramolecular
architecture with topological characteristics. In the topological gel, polymer chains with …

Self-Assembled Hexa-peri-hexabenzocoronene Graphitic Nanotube

…, T Fukushima, H Ichihara, T Shimomura, K Ito… - Science, 2004 - science.org
An amphiphilic hexa-peri-hexabenzocoronene self-assembles to form a π-electronic, discrete
nanotubular object. The object is characterized by an aspect ratio greater than 1000 and …

Structure and dynamics of polyrotaxane and slide-ring materials

K Mayumi, K Ito - Polymer, 2010 - Elsevier
Polyrotaxane (PR), in which cyclic molecules are threaded into a linear polymer chain, has
generated great interest because the sliding and rotation of the cyclic molecules on the axial …

Novel cross-linking concept of polymer network: synthesis, structure, and properties of slide-ring gels with freely movable junctions

K Ito - Polymer journal, 2007 - nature.com
We have recently developed a novel type of gel called the slide-ring gel or topological gel
that is different from physical and chemical gels by using the supramolecular architecture with …

[HTML][HTML] Extremely stretchable thermosensitive hydrogels by introducing slide-ring polyrotaxane cross-linkers and ionic groups into the polymer network

A Bin Imran, K Esaki, H Gotoh, T Seki, K Ito… - Nature …, 2014 - nature.com
Stimuli-sensitive hydrogels changing their volumes and shapes in response to various
stimulations have potential applications in multiple fields. However, these hydrogels have not yet …

Effective production of poly (3-alkylthiophene) nanofibers by means of whisker method using anisole solvent: Structural, optical, and electrical properties

…, T Shimomura, S Heike, T Hashizume, K Ito - …, 2008 - ACS Publications
The whisker method using anisole solvent was developed for effective production of high-aspect-ratio
poly (3-alkylthiophene) (P3AT) nanofibers, and alkyl chain length dependence on …
