Synthesis and antibacterial potential of hybrid nanocomposites based on polyorthochloroaniline/copper nanofiller
Bibliographic record
Abstract
Hybrid materials based on polyaniline derivative and metal nanofiller were reported for potential antibacterial applications. Polyorthochloroaniline/copper nanocomposites (POC/Cu NCs) were synthesized by in situ chemical oxidative polymerization of orthochloroaniline using ammonium persulfate as oxidant, in the presence of copper nanoparticles (CuNPs) and 4,4′‐diaminodiphenylamine. CuNPs were prepared through reduction of copper chloride by using sodium borohydride as reducing agent. The composition, structure, and morphology of CuNPs, POC, and their composites were characterized by UV–visible spectroscopy, Fourier transform infrared spectrometry, X‐ray diffractometry, and scanning electron microscopic techniques. The antibacterial potential of nanocomposites against gram‐positive bacteria ( Bacillus subtilis ) and gram‐negative bacteria ( Escherichia coli ) for various loads of copper nanofiller was evaluated using viable cell counts. The outcomes showed that nanocomposites have better antimicrobial efficacy than POC under the similar testing conditions. The mechanism of the synergistic antimicrobial effect of POC/Cu NCs was also proposed. POLYM. COMPOS., 39:4524–4531, 2018. © 2017 Society of Plastics Engineers

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
