  • Carbon nanotube compound and method for producing the same
    Patent number: 7923527
    Abstract: The invention provides a carbon nanotube compound and method for producing the same. The method of the invention comprises the following steps. Firstly, Aniline-trimer and DMAc(dimethyl acetamide) solution are mixed to form a first solution. Secondly, Dianhydride and DMAc solution are mixed to form a second solution. The first solution and the second are mixed to form a third solution. Additionally, carboxyl-multiwall carbon nanotubes (c-MWNT), Diaminodiphenylether and DMAc solution are mixed to form a fourth solution.

  • Preparation of supramolecular polymers containing sequence-selective hydrogen bonding subunits in their backbone which form double helices
    Patent number: 7919562
    Abstract: The present invention relates to supramolecular polymers containing sequence-selective hydrogen bonding subunits in their backbone which form double helices. The invention allows for tuning of the numbers and sequences of donor/acceptor units incorporated in any one crosslinking hydrogen bonding subunit and hence tuning of the interaction strength not only through the amount of crosslinking material incorporated but also through modulation of the strength of the crosslinking interactions. It also allows for the incorporation of more than one type of crosslinking agent in the material allowing for multiple strengths of crosslinking which are each tunable with regard to disruption from solvent, temperature and stress. Hydrogen bond strength between oligomeric chains can be tailored through modification of the numbers and sequences of the donors/acceptors in the oligomers.
