The resulting materials, comprising up to 94% biorenewable content, were flexible and cross-linked and had mechanical and thermal properties that varied with IU and GDLU content (e.g., rubbery plateau storage moduli = 6.1 to 10.5 MPa at 40 degrees C above the glass transition temperature; glass transition temperatures = -9.9 to 27 degrees C by differential scanning calorimetry; degradation temperatures = 238 to 347 degrees C by thermogravimetric analysis). By combining electrospinning with in-situ UV irradiation and carefully controlling the monomer mixture viscoelasticity and orifice-to-collector flight time, we produced uniformly cured fibers directly from the monomer feed when the ene monomers contained either 100% GDLU or 50% GDLU/50% IU. The resulting GDLU-containing thermoset films and fibers were readily decomposed into soluble small molecule fragments in basic aqueous media due to the intrinsic degradability of the GDLU unit. This study highlights the potential advantages of using carbohydrate-derived monomers for producing thermoset fibers and nonwovens that are both renewable and degradable.
