“…For example, it was reported that some antimicrobial materials might cause damage to human bodies while killing the microbes [11]. Also, some antimicrobial materials, once abandoned or released, could lead to environmental and ecological issues [12]. Therefore, it has become a consensus that antimicrobial materials, no matter how potent they are, should be less collateral damaging.…”

“…Therefore, it has become a consensus that antimicrobial materials, no matter how potent they are, should be less collateral damaging. Under this demand, biocompatible polymers-based antimicrobial materials (i.e., biocompatible antimicrobial polymers) have become more favorable among customers and markets, and this type of material has become a new area for research [12].…”

Antimicrobial materials have become an essential part of various fields. In the past decades, various types of antimicrobial materials were developed and practically used. Based on the feedback from the clinical usage and market, the biocompatible materials have been very welcomed due to less side effects. This chapter provides a small and general review of biocompatible polymer materials and their applications in antimicrobial fields. This chapter could be divided into several parts: starting from the background introduction of microbial threats, the first section discusses the demands of biocompatible polymers for antimicrobial applications, then, the following sections would describe the basic knowledge of biocompatible polymers, including the definition, advantages, and typical examples, the next section reviewed and discussed some approaches to apply biocompatible polymers into antimicrobial applications.

“…Marine biofouling is a major problem within a marine environment worldwide that affects the shipping industry and other maritime sectors, It refers to the attachment/adhesion and growth of marine organisms (ex: bacteria, barnacle, mussels) on the submerged sea surface and results in significant economic and environmental losses [1], [2].To address the challenge of minimizing the loss, antifouling coatings have been used as a noble fouling control system. [3] Fouling organisms can be easily removed from the surface if there are weak interactions between organisms and surface.…”

“…Here 𝑤 is an atomic weighting scheme (Z, m, v, e, p, i); 𝜋 𝑏 represents bond order (1-single, 2-double, 3triple, 1.5-aromatic); 𝑤 𝐶 is property on carbon atom; b is bond considered; dij is topological distance between i and j; 𝑤 𝑏(1) and 𝑤 𝑏(2) are properties of bonded atoms; summation considers shortest path from i to j with minimum sum if multiple paths exist. Higher value of this descriptor indicates presence of electronegative heteroatoms and less active power [88].…”

Polymer coatings with a fouling release activity is an effective method to prevent marine biological fouling caused by large number of marine organisms (over 4000) and ensure stability and safety of marine facilities. In this study, a novel cheminformatics-based approach was employed to investigate the fouling-release performance of siloxane-PU coating system. The structure-fouling release activity relationship was modeled for a set of 18 siloxane PU coatings by incorporation phenylmethyl silicones oils (PMM-1025, PMM-1043, PMM-5021, PMM-6025, PMM-0021, PMM-0025 of 1, 2 and 5 wt%). A specific structural descriptors encoding approach was applied for these systems, based on a mixture-based encoding, to feed the complex polymeric systems in machine learning algorithms. Several predictive quantitative structure-fouling release relationships models were developed using machine learning techniques, from multiple linear regression to nonlinear random forest methods, followed by scoring them based on high performance accuracy and validation with rigorous internal fit R2 train values between 0.73 to 0.95 and external predictivity R2ext between 0.68 to 0.88. Random Forest method was the best nonlinear one for predicting diatom removal activity. This work indicates that both linear and nonlinear machine learning-based modeling can be beneficial to predict fouling release properties of polymer coatings with an effective fouling release performance.

The Use of Tunable Encapsulation for Long-Term Fouling Control

Biofouling is a universal problem in the marine environment. Static structures and niche areas on ships, such as propellers, are not protected sufficiently by antifouling coatings. Encapsulation has previously been used as a fouling mitigation technique via application of an impermeable wrap or bag to a fouled hull or structure when it arrives in port or on station. This experiment investigated the use of a novel semipermeable encapsulation to proactively protect propeller mimics from biofouling. Sleeves were installed over propeller mimic panels and deployed in an active, multiuse port for 20 months. The sleeves completely prevented macrofouling on the panels for up to 13 months and maintained surfaces below 5% cover for the entire experimental period. This shows improvement over traditional antifouling without negative impacts on water quality like dissolved oxygen, pH, etc.
