Confined oil in beaded polymeric fibers with advanced thermoregulating properties
RPI ID: 2019-033-201, 2019-033-601 Innovation Summary: A coaxial wet-wet electrospinning process enables the creation of core-shell microfibers, where the core contains a phase-change material (PCM) like coconut oil and the shell is composed of cellulose. The fibers are extruded into an ethanol-water coagulation bath, forming a beaded morphology with...

Novel nanocomposite fibers with a dramatic reduction in human plasma coagulation time
RPI ID: 2019-034-401 Innovation Summary: This invention describes a method for producing cellulose-nanoclay hemostatic nanocomposite fibers. The process involves dissolving cellulose in a room-temperature ionic liquid and integrating nanoclay particles to form a homogenous solution. The resulting fibers exhibit dramatically reduced human plasma coagulation...

Solution Pulling-Drawing Device
Electrospinning has shown great promise in the manufacturing of nanofibers, yet the scalability of electrospinning has posed a number of challenges. These challenges include: Low fiber output per spinneret since solvent often makes up 70% of the solution mass, depending on the polymer and solvent system. Clogging of spinneret due to the solidification...
