摘要

In this work, silk was reacted with 2-bromoisobutyryl bromide to obtain silk macroinitiator for activators regenerated by electron transfer for atom transfer radical polymerization (ARGET ATRP). Silk macroinitiator was grafted with 2-hydroxyethyl methacrylate (HEMA) via ARGET ATRP method to produce grafted silk in water aqueous. FT-IR characterization of the modified silk substrate showed that HEMA had been grafted onto the silk surface. Scanning electron microscopy (SEM) photos of the grafted silks showed significant differences from the untreated silk. X-ray diffraction curves demonstrated that the crystalline structure of silk remained unchanged regardless of the HEMA grafting. Differential scanning calorimetry (DSC) curves indicated that the thermal stability of the grafted silk was improved. The whiteness, strength and moisture regain of the grafted silk decreased slightly, but the wrinkle recovery angle of the grafted silk increased distinctly compared with the control sample.
