Special Issue Information

Dear Colleagues,

Polymerization offers a powerful and modular strategy in generating macromolecules and structures with high complexity and versatile functionality. Smart and functional polymers, to which functional groups are chemically attached, have drawn growing interest as they hold considerable promise for a variety of applications. Smart polymers can be constructed via polymerization of functional monomers or post-polymerization modifications. These polymers possess the combination of the physical properties of nanoscale or microscale architectures and physiochemical reactivities of the attached functional groups. Moreover, their ability to form microscopic and macroscopic assemblies in response to external targets or signals renders unique physiochemical properties (e.g., large surface-to-volume ratio, variable composition and size, dynamic association, and reversible phase separation) and tailored functionalities (e.g., enhanced sensitivity and specificity, extraordinary target binding affinity, and tunable surface chemistry) that are absent in small molecules.

Smart and functional polymeric material is an interdisciplinary field that integrates physics, chemistry, material science, engineering, and biology. Over the past decade, the field has experienced rapid progress as a result of the push by unmet needs in various areas. This Special Issue aims to provide a comprehensive collection of the latest advances in the development of synthetic approaches, mechanism underlying structure-property correlations, and current and emerging applications of smart and functional polymers. The issue will cover smart and functional polymers for a diverse range of applications, involving but not limited in synthetic chemistry, analytical chemistry, materials science, environmental science, industrial fabrication, electronics, renewable energy, food science, agriculture, biomedical technology, and healthcare.

Considering your prominent contribution in this very active field of research, we would like to cordially invite you to submit an article to this Special Issue. Short communications, full research articles, and timely reviews are all welcome.

Thermosensitive gels are commonly used as drug carriers in medical fields, mainly due to their convenient processing and easy functionalization. However, their overall performance has been severely affected by their unsatisfying biocompatibility and biodegradability. To this end, we synthesized poly(l-alanine) (PLAla)-based thermosensitive hydrogels with different degrees of polymerization by ring-opening polymerization. The obtained mPEG45−PLAla copolymers showed distinct transition temperatures and degradation abilities. It was found that slight changes in the length of hydrophobic side groups had a decisive effect on the gelation behavior of the polypeptide hydrogel. Longer hydrophobic ends led to a lower gelation temperature of gel at the same concentration, which implied better gelation capability. The hydrogels showed rapid gelling, enhanced biocompatibility, and better degradability. Therefore, this thermosensitive hydrogel is a promising material for biomedical application. Full article
