Abstract:

Nanotechnology coupled with basic understanding of mechanical engineering can do wonder in our everyday technology. In this work it will be shown that how electrospinning and solution blowing can be used as perfect platform for preparing materials of nanoscale order. It will be shown that using electrospun nanofibers mat a heat flux removal rate ~1kW/cm2 can be achieved. It will also be shown that nanoencapsulation of phase change materials can be used for manipulation of temperature range of operation. Use of a novel solution blowing method in preparing functional nanomaterial starting from carbon nanotube to green sustainable material will also be discussed. Then use of rheology in understanding flow behaviour of complex fluid will be elucidated, which will be coupled with discussion on experimental and theoretical study of meltblowing, nanofluidics and manufacturing of stimuli responsive nanomaterial.
