Cobalt-incorporated poly(glycerol ester) (Co-PGE) was synthesized by the polycondensation of glycerol and adipic acid followed by the reaction with cobalt(II) hydroxide under solvent-free and noncatalyzed one-pot synthesis conditions. The reaction was monitored through the acid value and hydroxyl value determination. The chemical structure and molecular weight of the poly (glycerol ester) (PGE) and Co-PGE were characterized by Fourier transform infrared spectroscopy, 13 C-NMR, gel permeation chromatography, and inductively coupled plasma mass spectrometry. Co-PGE with a 59.3% degree of branching was incorporated with up to 5.0% w/w cobalt, and it exhibited antimicrobial inhibition against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans in a broth microdilution study. Polyurethane (PU) coatings were prepared by the blending of 0.5-35% w/w Co-PGE containing with 5% w/w of cobalt with blank PGE, poly(ethylene glycol) with a molecular weight of 6000, poly(caprolactone diol) with a molecular weight of 2000, and additives to react with isophorone diisocyanate. The prepared PUs demonstrated mild to high antimicrobial activities against E. coli, S. aureus, Bacillus subtilis, and C. albicans strains in a disc diffusion test. PU prepared with 0.5% w/w Co-PGE showed a mild inhibition activity against S. aureus, and PU prepared with 10% w/w Co-PGE demonstrated a high inhibition activity against C. albicans. This study demonstrated that value-added Co-PGE synthesized from glycerol has the potential as an antimicrobial agent for polymer coatings in biomedical devices. V C 2017 Wiley Periodicals, Inc. J.

“…Several reviews and articles discuss the development of luminescent chemo/ biosensors based on organometallic polymers. 9,40,[46][47][48][49][50] Organometallic polymers are also used as mechanical probes, 51 to fabricate sensitive membranes in surface acoustic wave devices for humidity sensing, [52][53][54][55] or in quartz crystal microbalance (QCM) devices to detect and quantify organic vapors. 56 Owing to the intrinsic redox and affinity properties of the metal, organometallic polymers have been employed in a variety of electrochemical sensors by detecting the current, redox potential or resistance changes of the sensing system.…”

Surface acoustic wave sensors are famous for its low cost, high resolution, and quick response time. In this paper, the SAW gas sensor for detecting low concentration of NH 3 was presented. The gas sensor array is composed of 2×2 non-continuously working oscillators equipped with one reference SAW sensor and three SAW sensors coated with different polymers. To improve the selectivity and sensitivity, ten kinds of polymers with special functional group were coated on the sensing area as the sensing film. The gas recognition database was established by collecting and normalizing the results of interplay between polymers and target gas. The miniaturized SAW chip was developed for low cost and portability, more capacities of polymer-coated SAW sensors mounted on a limited region of sensor array chip. The PNVP-coated miniaturized SAW sensor has been successfully developed to detecting low concentration ammonia of 16 ppm. Compared with the original SAW sensor, the miniaturized SAW sensor coated with PNVP film shows larger frequency shift but similar performance for low concentration of NH 3 detection after normalizing the results of interaction between polymer and ammonia.
