Thermal treatment of electrospun polystyrene fibers: microstructural evolution and mechanical behavior
The effects of thermal treatment on the microstructure and mechanical properties of electrospun polystyrene (PS) fibers were investigated. Two types of thermal treatments were performed: (1) slow cooling from 80 °C to room temperature, (2) constant-temperature annealing at 110 °C for 10–120 min. SEM...

description | The effects of thermal treatment on the microstructure and mechanical properties of electrospun polystyrene (PS) fibers were investigated. Two types of thermal treatments were performed: (1) slow cooling from 80 °C to room temperature, (2) constant-temperature annealing at 110 °C for 10–120 min. SEM images showed that the internal porosity of the fibers decreases with a decreasing cooling rate and with an increasing annealing time. The severity of fusion of the fiber mats during cutting decreased with a decreasing cooling rate and was eliminated by constant-temperature annealing at 110 °C for 10 min. N
2
-physisorption did not show any relationship between the cooling rate and porosity of the fibers, but it was found that the volumes of micro- and mesopores in the fibers decreased with an increasing annealing time. Uniaxial tensile testing showed a degradation in mechanical properties at a cooling rate of 0.1 °C s
−1
with a recovery in strength and ductility, but further degradation of stiffness at 0.03 °C s
−1
. Similar degradation of mechanical properties was found after annealing at 110 °C for 10 min, followed by a recovery of strength, stiffness, and ductility at 60 min. This work demonstrates that annealing PS fibers is a viable method to decrease the porosity and eliminate any potential fusion of electrospun PS fiber mats so they can be used in other manufacturing processes, such as ceramic processing.
