    摘要: 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.

    摘要: New carbon nanotube polymers and compositions are provided. The polymers comprise recurring blocks or units of carbon nanotubes and a compound other than a carbon nanotube. The compound is a polymeric or oligomeric block and is bonded to the carbon nanotube outer sidewall rather than to the carbon nanotube end, and is preferably a block copolymer of the compound and the carbon nanotube. The polymers can be used to prepare compositions that can be formed into products that are useful for building components present in airplanes.
