Patrick Mather has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10471648
    Abstract: A functionally graded shape memory polymer (SMP) that has a range of transition temperatures that are spatially distributed in a gradient fashion within one single article. The SMP is formed by post-curing a pre-cured glassy SMP in a linear temperature gradient that imposes different vitrification temperature limits at different positions along the gradient. Utilizing indentation-based surface shape memory coupled with optical measurements of photoelastic response, the capability of this material to respond over a wide range of thermal triggers is correlated with the graded glass transition behavior. This new class of SMP offers great potential for such applications as passive temperature sensing and precise control of shape evolution during a thermally triggered shape recovery.

  • Patent number: 9533469
    Abstract: A self-healing product having a shape memory component and a healing component interpenetrating the shape memory component to form a fibrous microstructure. The healing component is selected so as to diffuse into a defect when the area of the product with the defect is subject to a treatment. The components may be selected so that applying heat at a temperature at or above a melting temperature (Tm) and/or a glass transition temperature (Tg) for one or both of the shape memory component and the healing component causes shape memory transition and diffusion by the healing component. The self-healing product can form a coating or material layer to protect a substrate while also providing the healing properties responsive to the treatment.

  • Patent number: 9249254
    Abstract: A multi-block thermoplastic polyurethanes system which incorporates polyhedral oligomeric silsesquioxane into conventional biodegradable thermoplastic polyurethanes built up by poly(?-caproactone) and polyethylene glycol blocks, resulting in biostability. The multi-block thermoplastic polyurethanes are synthesized from lysine-diisocyanate with poly(?-caprolactone)-diol, polyhedral oligomeric silsesquioxane-diol, and poly(ethylene glycol) using a one-step synthesis process.

  • Publication number: 20150343749
    Abstract: A structural shape memory assisted self-healing polymer formed by laminating thin layers of an ionomer, such as a member of the poly(styrene sulfonate) (PSS) family of ionomers, with a WEGP-type SMP, such as atactic poly(styrene) (PS) with molecular weight in the 200 kDa range (or alternatively poly(methyl methacrylate) (PMMA)) in combination with polycyclooctene (PCO). The self-healing polymer may also comprise an interpenetrating, immiscible polymer network (IPN) based on a blend of polystyrene and polystyrene sulfonate (PSS).

  • Patent number: 8683798
    Abstract: Embodiments of a product such as a stimuli-responsive product can comprise a shape memory component and a nanofiber component that forms a fibrous microstructure or network. The resulting product can be responsive to stimuli, such as electrical stimuli, in a manner that cause the product to deform, deflect, and rebound. In one embodiment, the product can comprise an epoxy and a continuous non-woven nanofiber, the combination of which provides a product with enhanced actuation speed.

  • Patent number: 8394393
    Abstract: A composite material containing polymeric nanofibers, themselves containing NO-donor molecules, imbibed with an elastomer matrix is permeable to both water and gas so that dissociation reactions in the presence of water releases NO gas in a sustained manner. The NO-donor nanofibers may be formed by synthesizing acceptable NO-donor molecules, blending such molecules in solution with PVP, PCL or PVAc, electrospinning the blend at relatively high voltage for form fiber mats, applying PDMS rubber to the fiber mat and crosslinking it. The resulting NO-releasing electrospun fiber composite may be used in medical devices such as catheters, stents, or vascular grafts, with the purpose of releasing nitric oxide within a controlled rate and for a sustained period of time, as well as other known medical applications for NO.
