The present invention relates to shape memory polymers and waterborne coating materials and, more particularly, to waterborne shape memory polymer coatings.

Waterborne shape memory polymer coatings

A fibrous structure. The fibrous structure can be a paper product treated with a waterborne shape memory polymer. The waterborne shape memory polymer can include structural units, wherein each structural unit comprises:

Fibrous paper structures utilizing waterborne shape memory polymers

The invention relates to the making of a cellulosic fibrous structure by adding a waterborne shape memory polymer to cellulosic papermaking slurry and forming a web from the waterborne shape memory polymer containing slurry. The web can be optionally foreshortened.

Methods for making fibrous paper structures utilizing waterborne shape memory polymers

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.
