Temperature buffering capacity of silk hydrogel: A useful packaging material

摘要

The n-octadecane incorporated silk hydrogel is developed by the gelation of an o/w emulsion made of n-octadecane and the aqueous silk solution acting as the oil and water phases, respectively. SEM images show that n-octadecane grains can be clearly observed in the pores of the lyophilized hydrogel, which indicates the successful embedment of n-octadecane in the composite hydrogel. Furthermore, the composite hydrogel exhibits good water absorption capability and thermal regulation capacity. Therefore the silk composite hydrogel can be a promising candidate as the potential packaging structures for temperature sensitive materials. (C) 2017 Elsevier B.V. All rights reserved.
