Artykuł stanowi przegląd literaturowy dotyczący zastosowań elastomerów biobójczych w zapobieganiu infekcjom. Opisano przyczyny infekcji bakteryjnych, zwłaszcza wywoływanych przez bakterie wielooporne, a także sposoby im zapobiegania. Scharakteryzowano stosowane rodzaje powłok biobójczych. Przedstawiono działanie elastomerów o właściwościach biobójczych, a także wymagania związane z technologią gumy, które musi spełniać substancja biobójcza stosowana w elastomerach.

“…By contrast, polystyrene nanoparticles did not form in the polyelectrolyte network of cross-linked poly(NIPAm- co -methacrylic acid) . It is believed that raspberry-shaped particles are important in applications such as superhydrophobic coatings, − high-performance catalysts, , and antibacterial agents because of their high surface area and roughness. Therefore, clarifying the details of seeded emulsion polymerization in the presence of microgels and controlling the morphology (i.e., surface roughness, internal structure, softness) of stimuli-responsive raspberry-shaped composite microgels are important research topics.…”

A series of raspberry-shaped composite microgels were synthesized by seeded emulsion polymerization of styrene in the presence of hydrogel particles with different distributions of charged groups. Unlike microgels whose charged groups are localized in their center,29 polystyrene nanoparticles were formed inside the core microgels when the microgels whose charged groups were localized on their surface were used as cores for seeded emulsion polymerization. The effects of the surface charge densities of the core microgels and the concentration of styrene monomer during the polymerization on the resultant structures of composite microgels were investigated. The surface structures of obtained composite microgels were mainly evaluated by electron microscopy, and their stimuli responsiveness was evaluated by dynamic light scattering and laser Doppler velocimetry. The internal structures of the composite microgels were visualized from ultrathin cross sections observed by transmission electron microscopy (TEM). Cryo-TEM was used to clarify the microscopic structures of composite microgels when they were in hydrated states. Through a series of characterizations, we summarize the effects of structures of core microgels on the resultant composite structures.

“…Natural rubber latex (NRL), extracted from Hevea brasiliensis tree, are widely used in manufacturing dipped products such as medical gloves, balloons, and condoms due to its low cost, excellent elasticity, and film‐forming property. However, the poor tensile strength of unvulcanized NRL film is a serious defect and limits its application in certain areas.…”

Na-montmorillonite/polyethyleneimine-g-poly(methyl methacrylate) (Na-MMT/PEI-g-PMMA) nanocomposite latexes were prepared by soap-free emulsion polymerization in the aqueous suspension of Na-MMT. The exfoliated morphology of the nanocomposites was confirmed by XRD and TEM. With the aim of improving morphology and mechanical properties of natural rubber latex (NRL) films, the synthesized Na-MMT/PEI-g-PMMA nanocomposites were mixed with NRL by latex compounding technology. The results of SEM and AFM analysis showed that the surface of NRL/Na-MMT/PEI-g-PMMA film was smoother and denser than that of pristine NRL film while Na-MMT was dispersed uniformly on the fracture surface of the modified films, which suggested the good compatibility between NRL and Na-MMT/PEI-g-PMMA. The tensile strength of NRL/Na-MMT/PEI-g-PMMA films was increased greatly by 85% with 10 phr Na-MMT/PEI-g-PMMA when Na-MMT content was 3 wt % and the elongation at break also increased from 930% to 1073% at the same time.The purpose of this work was to investigate the effects of Namontmorillonite/polyethyleneimine-g-poly(methyl methacrylate) (Na-MMT/PEI-g-PMMA) nanocomposites on the morphology and mechanical properties of NRL films. Na-MMT/PEI-g-PMMA nanocomposite latexes were prepared by soap-free emulsion polymerization. 23,24 An amphipathic macromolecule PEI was introduced into the gallery of Na-MMT and formed
