Poly(N-vinylcaprolactam), a comprehensive review on a thermoresponsive polymer becoming popular

Poly(N-vinylcaprolactam) (PNVCL) is a thermoresponsive and biocompatible polymer that raises an increasing interest in the biomedical area, especially in drug delivery systems (DDS) that include micelles, hydrogels, and hybrid particles. The thermoresponsiveness of PNVCL, used alone or in combination with other stimuli- responsive polymers or particles (pH, magnetic field, or chemicals), is often key in the loading and/or release process in these DDS. The renewed focus on this polymer, which is known for decades, is to a large extent due to recent progress in synthetic strategies. Especially, the advent of efficient controlled radical polymerization (CRP) methods for NVCL monomer gives now access to unprecedented well-defined NVCL-based copolymers with unique properties. This Review article addresses up-to-date synthetic aspects, biological features, and biomedical applications of the latest NVCL-containing systems.

The normalized damage function based on elastic modulus is proposed to evaluate damage for ductile metals under a unified criterion. An equivalent half-sine model is employed to illustrate plastic stress–strain relationship. Toughness indicator is introduced to describe the toughness character in metals. An exponential rule is employed to calculate toughness indicator, and the parameter of toughness indicator is formulated by conventional mechanical properties of metals. Repeated loading–unloading tensile tests are conducted on stainless steel and aluminium alloy. The good correlation coefficient and dispersion are presented between the experimental values and predicted values of damage variable (within 12%). The damage function with toughness indicator can be applied to predict the effective elastic modulus.
