Show moreThe functional gradient materials have been widely used in chemical engineering, biomedical engineering and tissue engineering since they have been reported because of their admirable mechanical, physical and chemical properties. Several traditional methods of synthesis gradient materials are known to all. Here we introduced a new mathematical model of designing and producing crosslinked polymeric films with target multiple gradients. We derive our model from batch reactor system and explore how each condition of the system affects the gradient of the polymer film. Then we extend to semi-batch reactor to control the gradient in crosslink density and set up different strategies to make the target multiple gradient crosslink density accomplish. With any given target gradient crosslinked polymer film, we can make an exact similar film in our model. M.S. in Chemical Engineering, May 2014 Show less
