Molecular weight of polymers dissolved in a solvent substantially influences a range of concentrations suitable for obtaining smooth electrospun nanofibres. A change in molecular weight also results in a change of viscosity of the corresponding initial polymer solution, and consequently in a thickness (diameter) of the resulting nanofibres. Fixing the entry parameters of an electrospinning process such as temperature, humidity, voltage and a tip-to-collector distance, relatively simple algebraic expressions relating molecular weight, concentration, viscosity and nanofibre diameters are presented.
