Abstract
Methods and apparatus for forming non-woven fiber mats from polymers and monomers that are traditionally difficult to use for fiber formation are shown and described. Applicable techniques include electrospinning and other traditional fiber formation methods. Suitable polymers and monomers include those having low molecular weight, a low melting point, and/or a low glass transition temperature.
Claims15
A non-woven fiber mat formed of fibers, wherein the fibers comprise low molecular weight polymers or oligomers formed from a low molecular weight polymer precursor selected from the group consisting of:
- Poly (propylene-fumarate)-co-(propylene maleate) (PPFcPM);
- Poly (Butylene-fumarate) (PBF);
- and Poly (Butylene-fumarate)-co(butylene maleate) (PBFcBM);
- and a covalent cross-linker or photoinitiator.
