This paper deals with modeling the electrospinning nanoporous materials process. The presented theoretical models offer an in-depth insight into the physical understanding of many complex phenomena and might be very useful at shedding light on the contributing factors. Many basic properties and some special properties (such as the numbers and sizes of the pores) are tunable by adjusting electrospinning parameters such as voltage, flow rate, and others. With the increase of voltage and the decrease of flow rate, ever-increasing numbers and ever-decreasing sizes of the nanoporous microspheres have appeared. Electrospun nanoporous materials which can be regarded as thousands of Helmholtz Resonators forming together will become a kind of excellent sound absorption material. (C) 2012 Elsevier Ltd.
