“…The agglomeration of the BC particles caused partially separation of micro-spaces between particle and particle, and particle and polymer and thus, obstructed stress propagation when tensile stress was loaded [53]. [15,41].…”

“…Spraying 2-hydroxypropyl trimethylammonium chloride chitosan (HACC) onto the softwood pulp to prepare antibacterial paper is one of the methods (Zhang and Guo 2008). Moreover, chitosan/bamboo charcoal composite films have been prepared using a spin coater machine (Nitayaphat et al 2009). Recently, N, O-carboxymethyl chitosan (N, O-CMCS) has been combined with bamboo fiber to prepare blended films (Zheng et al 2014).…”

To obtain a functional composite paper with antibacterial activity, 2-hydroxypropyl trimethylammonium chloride chitosan (HACC) was prepared and sprayed onto the surface of paper made of bamboo fiber. HACC was synthesized from chitosan with 2,3-epoxypropyl trimethylammonium chloride (GTAMC), and the optimal preparation conditions were selected by single-factor tests. The highest degree of substitution (DS) of HACC reached 0.868, when the ratio of chitosan to GTAMC was 1:4, and the water solubility was noticeably improved. The structural characterization demonstrated the successful modification on the original chitosan with a decrease in heat stability and the peak correlated with hydroxypropyl trimethylammonium chloride groups in FTIR. The addition of HACC in the bamboo fiber paper greatly increased the antibacterial activity, and water absorption was higher as well. These results may serve as a basis for the modification and the preparation of chitosan antibacterial agents.

“…In the latter case, different administration routes and uses such as buccal delivery of flufenamic (10), control release of amoxicillin in stomach for the treatment of Helicobacter pylori (11), vaginal delivery of metronidazole for the treatment of bacterial vaginosis (12), or potential skin drug delivery systems (13) were evaluated. Several works have studied the mechanical properties of CH films, demonstrating that these properties may be improved when CH forms polyelectrolyte complexes with other polymers oppositely charged (14,15). Carbopol 971NF (CB) is a useful polymer which may be anionic, depending on the pH value, and therefore it may generate ionic interactions with CH.…”

Design, Characterization, and In Vitro Evaluation of Antifungal Polymeric Films

Abstract. The objective of the present paper was the development and the full characterization of antifungal films. Econazole nitrate (ECN) was loaded in a polymeric matrix formed by chitosan (CH) and carbopol 971NF (CB). Polyethylene glycol 400 and sorbitol were used as plasticizing agents. The mechanical properties of films were poorer when the drug was loaded, probably because crystals of ENC produces network outages and therefore reduces the polymeric interactions between the polymers. Polymers-ECN and CH-CB interactions were analyzed by Fourier-transform infrared spectroscopy (FTIR), thermal gravimetry analysis, and differential thermal analysis (DTA-TGA). ECN did not show structure alterations when loaded into the films. In scanning electron microphotographs and atomic force microscopy analysis, films prepared with CB showed an evident wrinkle pattern probably due to the strong interactions between the polymers, which were observed by FTIR and DTA-TGA. The in vitro activity of the formulations against Candida krusei and Candida parapsilosis was twice as greater as the commercial cream, probably as a result of the antifungal combination of the drug with the CH activity. All these results suggest that these polymeric films containing ECN are potential candidates in view of alternatives dosages forms for the treatment of the yeast assayed.
