  • Publication number: 20140242623
    Abstract: We disclose methods and compositions for preparation of stimuli-responsive plastics that are capable of responding to chemical and/or physical signals in their environment. In one embodiment the plastics consist of patterned mixtures of poly(phthalaldehyde) polymers in which each polymer contains a different end-capping group (also called a “trigger”), responsive to a different signal. Other embodiments use different polymers and different triggers. The plastics may be homogeneous in composition, but each polymer within the plastic is capable of responding to a different signal and depolymerizing once this signal reacts with the trigger. This process of depolymerization enables the plastic to alter its physical features non-linearly to external signals: i.e., the degree of change in physical form is much larger than the intensity of the initial signal.

  • 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.

  • Publication number: 20100009256
    Abstract: Disclosed is a composite body of an electrode active material and a conductivity-imparting agent, which has high capacity density and enables to take out a large current. Also disclosed are a method for producing such a composite body, and a battery having high energy density and a large output power. Specifically, a polyradical compound as an electrode active material and a conductive material are heated and mixed at a temperature not less than the softening temperature but less than the decomposition temperature of the polyradical compound, thereby for forming a composite body of the polyradical compound and the conductive material. By producing an electrode using such a composite body, there can be obtained a novel battery having high energy density and large output power.
