Abstract:The aim of this study was to find alternative starch plasticizers
to glycerol that yielded a less tacky material in high-moisture conditions
without leading to starch crystallization. A range of glycerol films
containing different potential plasticizers (linear alkane diols)
were therefore produced, and it was shown that 1,3-propanediol, in
combination with glycerol, was a possible solution to the problem.
Several additional interesting features of the starch films were however
also revealed. The larger diols,… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
