Abstract Although the natural silk has good and unique performance, there are several physical defects, such as poor mechanical properties (tensile strength and toughness), short life time and poor color fastness. Scientists have developed new technologies of silk modifications to improve their performance and achieve better applications. At present, the commonly used methods of silk modifications mainly include gene modification method, physical method, chemical method, and feeding method. In this short review, firstly, the structure of silk and their modification principle are summarized, and then the important progress made in recent years on the four kinds of modification methods are introduced. Finally, the challenges on modified silk field and the future development are prospected.
