Therefore, cellulose diacetate is functionalized with thiol moieties and olefinic or methacrylic side groups enabling thiol-conjugated cross-linking. These cellulose derivatives are also photo-cross-linkable via UV irradiation (𝜆=254nm and 365 nm) without using an initiator.enOpticsApplied PhysicsDDC::500 Naturwissenschaften und Mathematikjournal article
