Conventional antibiotics has saved countless human lives, however, is seriously challenged by the quick emergence of antibiotic-resistant pathogens. It is urgent to develop new types of antimicrobial agents to treat antibiotic-resistant microbial infections. Host defense peptides (HDPs) have broad-spectrum antimicrobial activity and low susceptibility to antimicrobial resistance, therefore, have been actively studied to develop promising antimicrobial agents. However, natural HDPs are structurally unstable due to their easy hydrolysis by proteases. Sequence-defined peptides have been explored as HDP mimics and have proven as promising candidates of antimicrobial drugs. Nevertheless, preparation of these HDP-mimicking peptides by solid-phase synthesis is time-consuming, expensive, and difficult for large scale synthesis.

Amino acid polymers, also known as poly(amino acid)s, have the same or similar backbone structure as natural peptides and have excellent biocompatibility. Several classes of such antimicrobial polymers have been explored as synthetic mimics of HDPs including α-amino acid polymers, β-amino acid polymers, peptoid polymers, amino acid hybrid polymers, and peptide mimicking polymers such as poly(2-oxazoline)s. To tune the biological activities and obtain the optimal antimicrobial polymers, key structure characteristics of HDPs are involved and investigated such as positive charges and the hydrophobic/hydrophilic amphiphilic structure. In this review, we provide an overview of research in the last decade about the design of HDP-mimicking antimicrobial amino acid polymers and beyond, including positive charge, amphiphilic structure, chain length, end group, </span></span>hydrophilicity<span>, stereochemistry<span>, secondary structure, topology, self-assembly and backbone structure, as well as the major applications of antimicrobial amino acid polymers.

These crystallized polymers undergo various deformations under different external fields (<em>e.g.</em><span>, stretching) from precursor processing, post treatment to final shape formation. Such deformation process is accompanied by multi-scale and multi-stage structural evolutions due to the complex hierarchical structures of crystallized polymers. These structural evolutions control over essential physical properties of semicrystalline polymers, which can be further developed towards high-performance industrial materials. A profound understanding of associated mechanisms is the critical key to interpret the complicated deformation process and to optimize the practical performances of polymer materials. The past reviews have more or less focused on one aspect of deformation while the multi-scale vision is lacking. Herein, this review brings a comprehensive presentation of strain-induced structural mechanics of crystallized polymers based on a multi-scale, multi-stage standpoint from the initiation of plasticity until failure. Important structural changes and associated mechanisms during the whole deformation process are systematically summarized, with particular attention paid to the crystal phase transition and crystal morphology evolution. Besides, the relationships between resulted microstructures and the essential end-use properties of crystallized polymers as well as their performances as common industrial materials are discussed.

Many methods have already been reported for the synthesis of degradable heteroatom-containing polymers based mainly on conventional step-growth polymerization and chain-growth ring-opening polymerization (ROP). In recent years, ring-opening metathesis polymerization (ROMP) has evolved as an emerging approach for the synthesis of various types of degradable polymers, from carbocyclic norbornene derivatives to heterocyclic olefin monomers. Classic ruthenium (Ru)-based catalysts exhibit not only high reactivity to C=C double bonds but also high tolerance to polar functional groups. Hence, a rich range of functional groups can be incorporated into cyclic olefin monomers and then transferred to the polymer backbones.
