What was your inspiration in becoming a chemist?

I wanted to make new materials for us to have better lives and a greener world.

What was the motivation to write your Polymer Chemistry article?

Supramolecular crosslinked polymer gels have tremendous potential as smart materials because they offer a special combination of the elastic behaviour of solids and the microviscous properties of fluids. From many published reports related to supramolecular crosslinked polymer gels, one can reach two general conclusions: 1) there are many kinds of non-convalent interactions that can be used to crosslink polymeric chains to yield supramolecular gels and 2) usually these supramolecular gels contain only one kind of noncovalent crosslink. The consequence of using a single type of supramolecular crosslink is that above some level of external stimulation, sufficient cross-links are broken and subsequently a gel to sol transition usually occurs. This transition, which can occur across a narrow stimulus window, can limit applications in several ways. In order to solve this problem, we are interested in the fabrication of supramolecular crosslinked polymer gels containing two types of physical crosslinks based on two orthogonal supramolecular interactions. In such a system, one supramolecular crosslink can be used to maintain the gel state and the other to change the crosslinking density of the gel under external stimuli, thereby giving rise to the macroscale expansion-contraction behaviour of the gel without the gel-sol transition. The roles of the two networks can be reversed, allowing for a multi-responsive, expansion-contraction system that will be more adaptive. Finally, addition of both stimuli will allow breakdown of the gel. In this Polymer Chemistry article, we report that exactly such a double supramolecular crosslinked polymer gel based on hydrogen bonding and a macrocycle threading process achieves these properties.

Why did you choose Polymer Chemistry to publish your work?

Firstly, Polymer Chemistry is a very good journal and it is great to publish my work in it. Secondly, I am an Advisory Board member for Polymer Chemistry and I want to contribute to the development of this journal.

In which upcoming conferences may our readers meet you?

I am attending the First Artificial Molecular Switches and Motors Gordon Research Conference which will be held at Stonehill College, Easton, MA (USA) on 7th-12th June 2015. Follow the link for more information about this conference.

How do you spend your spare time?

Playing with my son, reading, listen to music, and travelling.

Which profession would you choose if you were not a scientist?

I would be a high-school teacher because I want to work with and help young people.

A double supramolecular crosslinked polymer gel exhibiting macroscale expansion and contraction behavior and multistimuli responsiveness

Xiaofan Ji, Kecheng Jie, Steve Zimmerman and Feihe Huang

Supramolecular crosslinked polymer gels show special properties largely as a result of the combined mechanical properties contributed by the covalently linked polymer chains and the reversible, stimuli-responsive supramolecular crosslinks. Most supramolecular crosslinked polymer gels contain only one kind of physical cross-link. Herein we report a novel supramolecular polymer gel containing two types of physical crosslinks based on two kinds of non-covalent interactions that are orthogonal: DAN-DeUG quadruply hydrogen-bonding interactions and benzo-21-crown-7/dialkylammonium salt host-guest interactions. One of the crosslinked networks is used to maintain the gel state while the other modulates the crosslink density through an external stimuli, thereby causing a volume change of the gel. This double supramolecular crosslinked polymer gel shows macroscale expansion and contraction behaviour and multistimuli responsiveness. Therefore, we successfully demonstrate that the macroscopic property changes of supramolecular systems can be induced by controlled self-assembly on the molecular scale.
