Design of digital thermometer and application in electrospinning

摘要

Electrospinning is currently available one of the best fibre forming technology with many advantages over previously available methods. But still this process requires a lot of optimization. In my project I mainly focused on design of digital thermometer which can be further used for real time temperature measurement during the run of electrospinning process. LM 35 sensor and At-mega 32 microcontroller was used. Seven segment display is used for the display of temperature. The thesis mainly covers the basics of electrospinning, factors affecting it and how to control the parameters for its optimization. But mainly the thesis focused on the design of digital thermometer. At different temperature SEM of fibre produced were taken and it was observed that at higher temperature fibre diameter decreases .So temperature control is an important aspect in electrospinning to control fibre diameter and for production of smooth fibers.
