Abstract
Abstract Water-induced shape memory polymers (SMPs) are the desired candidates for the uses in the fields of surgical operation, smart textile, and aerospace. However, most of water-induced SMPs are non-biodegradable petroleum-based polymers, and a quick response to water of SMPs is usually accompanied with the loss of wet strength due to the over hydration. To address this issue, in this work, a water resistant cellulose nanopaper (CNP) was firstly prepared with the cellulose nanofibrils (CNFs) produced by formic acid hydrolysis, and then the obtained CNP was modified via immersing in chitosan (CS) for the preparation of a robust CNP with quick water and humidity responses. Results showed that the original shape of the modified CNP after folding could immediately respond to water (
