“…The tested phenolic structures have pronounced antibacterial features against various bacterial strains, and exert strong pharmacological activities such as flavouring, antioxidant and antiseptic characteristics, has already been reported elsewhere [13,14]. In continuation of our previous study [3], herein, we report a new study on the development of bio-composites with novel characteristics through enzymatic grafting.…”

A series of bio-composites including poly3-hydroxybutyrate [P(3HB)] grafted ethyl cellulose (EC) stated as P(3HB)-EC were successfully synthesised. Furthermore, natural phenols e.g., p-4-hydroxybenzoic acid (HBA) and ferulic acid (FA) were grafted onto the newly developed P(3HB)-EC-based bio-composites under laccase-assisted environment without the use of additional initiators or crosslinking agents. The phenol grafted bio-composites were critically evaluated for their antibacterial and biocompatibility features as well as their degradability in soil. In particular, the results of the antibacterial evaluation for the newly developed bio-composites indicated that 20HBA-g-P(3HB)-EC and 15FA-g-P(3HB)-EC bio-composites exerted strong bactericidal and bacteriostatic activity against Gram(-)E. coli NTCT 10418 as compared to the Gram(+)B. subtilis NCTC 3610. This study shows further that at various phenolic concentrations the newly synthesised bio-composites remained cytocompatible with human keratinocyte-like HaCaT skin cells, as 100% cell viability was recorded, in vitro. As for the degradation, an increase in the degradation rate was recorded during the soil burial analyses over a period of 42 days. These findings suggest that the reported bio-composites have great potential for use in wound healing; covering the affected skin area which may favour tissue repair over shorter periods.

“…Therefore, the reduced contact angle and increased wettability of the plasma-pretreated sample might be attributed to oxygen-containing surfaces induced by oxygen plasma treatment. As a result, the adhesion between the printing paste and cotton fibre surfaces would be enhanced (Shahidi et al 2010;Shateri Khalil-Abad et al 2009;Fras Zemljic et al 2009). …”

Using atmospheric pressure plasma for enhancing the deposition of printing paste on cotton fabric for digital ink-jet printing

2011

Atmospheric pressure plasma (APP) treatment was applied as a pretreatment process to enhance the deposition of printing paste in order to improve the final colour properties of digital ink-jet printed cotton fabrics. Three printing pastes containing natural polymers, i.e. (1) sodium alginate, (2) chitosan and (3) sodium alginate-chitosan mixture, were prepared separately. After APP treatment, cotton fabric was padded with different printing pastes prior to digital ink-jet printing. Experimental results showed that APP pretreatment could increase the colour yield of the digital ink-jet printed cotton fabric significantly even after washing. In addition, other properties such as colour fastness to crocking, colour fastness to laundering, outline sharpness and anti-bacterial properties were also improved when compared with those of the control cotton fabric printed without APP pretreatment. However, the influence of printing paste on the colour properties of the digital ink-jet printed cotton fabrics depended very much on the composition of the printing paste. The scanning electron microscope images evidenced that the APP treatment could enhance the deposition of printing paste on the cotton fabric surface as proved qualitatively by both the contact angle and wetting time measurement as well as quantitatively by both the X-ray photoelectron spectroscopy and carboxyl group/nitrogen content analysis.

“…In comparison to the untreated caffeic acid as shown in Figure 2, an increase in the absorbance at 1720 cm -1 (C=O) band, and 1050-1300 cm -1 (C-O) was noticed. The -OH bands overlapped in the 3400 cm -1 region, whereas, the peaks at 3396 cm -1 and in a broad 3100-3470 cm -1 region can be attributed to -OH, stretch [19,20]. In Figure 2, CA-loaded composites shows a band at 3345 cm -1 corresponding to phenolic -OH stretching involving hydrogen bonding, and a peak at 1360 cm -1 corresponds to -OH bending of the phenolic group [21].…”

Abstract.We have developed novel composites by grafting caffeic acid (CA) onto the P(3HB)-EC based material and laccase from Trametes versicolor was used for grafting purposes. The resulting composites were designated as CA-g-P(3HB)-EC i.e., P(3HB)-EC (control), 5CA-g-P(3HB)-EC, 10CA-g-P(3HB)-EC, 15CA-g-P(3HB)-EC and 20CA-g-P(3HB)-EC. FT-IR (Fourier-transform infrared spectroscopy) was used to examine the functional and elemental groups of the control and laccase-assisted graft composites. Evidently, 15CA-g-P(3HB)-EC composite exhibited resilient antibacterial activity against Gram-positive and Gram-negative bacterial strains. Moreover, a significant level of biocompatibility and biodegradability of the CA-g-P(3HB)-EC composites was also achieved with the human keratinocytes-like HaCaT cells and soil burial evaluation, respectively. In conclusion, the newly developed novel composites with multi characteristics could well represent the new wave of biomaterials for medical applications, and more specifically have promising future in the infection free would dressings, burn and/or skin regeneration field due to their sophisticated characteristics.
