Flavonoids as Visible Light Photoinitiators
The design of biosourced and/or bioinspired photoinitiators is an active research field as it offers a unique opportunity to develop photoinitiating systems exhibiting better biocompatibility as well as reduced toxicity. In this field, flavonoids can be found in numerous fruits and vegetables so these structures can be of interest for developing, in the future, polymerization processes, offering a reduced environmental impact but also better biocompatibility of the polymers.

Flame Retarding Mechanism of P-FRs in Polyurethane Elastomer
Polyurethane elastomer (PUE) is a typical block polymer with alternately arranges soft and hard segments. Isocyanates and small molecular chain extenders constitute the hard segment, and the soft segment is composed of polyols. Most phosphorous flame retardants for PUE exhibit two flame-retardant mechanisms, including the gas phase and the condensed phase.

Fireproof Nanocomposite Polyurethane Foams
First introduced in 1954, polyurethane foams rapidly became popular because of light weight, high chemical stability, and outstanding sound and thermal insulation properties. Currently, polyurethane foam is widely applied in industrial and household products. Despite tremendous progress in the development of various formulations of versatile foams, their use is hindered due to high flammability. Fire retardant additives can be introduced into polyurethane foams to enhance their fireproof properties. Nanoscale materials employed as fire-retardant components of polyurethane foams have the potential to overcome this problem.

Filled Polymers and DMA
Dynamic mechanical analysis (DMA) provides reliable information about the viscoelastic behavior of neat and filled polymers. The properties of filled polymers are relevant to different industries as protective organic coatings, composites etc. Interfacial interactions in filled polymers play an important role in determining their bulk properties and performance during service life. In this entry, studies which used DMA to characterize the interfacial interactions in filled polymers have been reviewed.

Fabrication-4D-Printed Shape Memory Polymers
Additive manufacturing (AM) is the process through which components/structures are produced layer-by-layer. In this context, 4D printing combines 3D printing with time so that this combination results in additively manufactured components that respond to external stimuli and, consequently, change their shape/volume or modify their mechanical properties. Therefore, 4D printing uses shape-memory materials that react to external stimuli such as pH, humidity, and temperature. Among the possible materials with shape memory effect (SME), the most suitable for additive manufacturing are shape memory polymers (SMPs).

Excipients in Pharmaceutical Additive Manufacturing
Additive manufacturing (AM), popularly known as three-dimensional printing (3DP), has been widely applied to the fabrication of prototypes through to functional parts in various manufacturing areas, including the pharmaceutical industry. The term “3D printing” technically refers to a broad collection of additive technologies based on the deposition of materials, like creating objects from the bottom up or layer by layer. Despite the technical differentiation between the terms, “3D printing” has become the common term.
