Embodiment 1

[0106] experimental method

[0107] Preparation of Citrox Precursor: Citrox HXT powder was dissolved in methanol. The precursors were formulated using either 10 wt% or 15 wt% Citrox in methanol.

[0108] Pretreatment of samples: Preliminary He / O with or without polyethylene terephthalate (PET) films and silicon wafers 2 Plasma pretreatment.

[0109] In atmospheric plasma jet processing systems (e.g. PlasmaStream TM ), 5% O in He was used through two rounds 2 The resulting plasma activated substrate. The applied plasma powder was 80%, the CNC speed was 7 mm / sec, and the distance from the substrate to the plasma jet orifice was 10 mm.

[0110] In reel-to-reel atmospheric plasmas (e.g. Labline TM In the case of system), an O2 containing 5% of He in 2 The processing chamber is passed three times to activate the substrate. The applied plasma powder was 1000 W and the sample was passed through the chamber at a speed of 1.5 m / sec.

[0111] Import into PlasmaStream using TM ...

Embodiment 2

[0155] Impregnation of polystyrene sheets with Citrox

[0156] Polystyrene sheets were treated using plasma immersion ion implantation (PIII) with nitrogen ions at an energy of 20 keV for 800 seconds to form a surface embedded with groups capable of covalently binding bioactive molecules (as in Bilek et al., PNAS, 08( 35):14405-14410, 2011, which is hereby incorporated by reference). PIII-treated and untreated sheets were incubated for 3 hours in tubes filled with Citrox concentrate (PHLC 45) or deionized water (for controls). Contains bioflavonoids in HPLC 45 or "Citrox BC" 45% (total composition of HPLC 45 / Citrox BC). The bioflavonoids were in admixture with biomass residues extracted from bitter oranges such as pectin, sugars and small amounts of organic acids (which constituted the remaining 55%). HPLC 45 is available from Exquim (a company of Grupo Ferrer) as Citrus BioflavonoidComplex 45% HPLC. After incubation, the sheets were washed thoroughly in the tubes with deio...

Abstract

The present invention describes a polymeric material having a bioflavonoid coating, said bioflavonoid content of said coating comprising at least naringin and neohesperidin. Applications of these coated polymeric materials and methods for preparing said coated polymeric materials are also described.

Description

technical field [0001] The present invention relates to polymeric materials, methods for coating polymeric materials and uses thereof. More specifically, the present invention relates to polymeric materials with bioflavonoid coatings. Background technique [0002] Polymers form a huge range of materials and exhibit a wide variety of properties. Polymers can be synthetic, natural or semi-synthetic. Because of their properties such as thermal stability, strength and thermal insulation, polymeric materials have many applications and are an integral part of industry and everyday life. [0003] Certain synthetic polymer products would benefit from having antimicrobial properties. These include for example food packaging and packaging for meat and soft fruit, in particular medical devices such as catheters, masks such as breathing masks and various polymer products used in hospitals, nursing homes and nurseries. [0004] GB2468836 discloses compositions comprising bioflavonoid...
