▎ 摘 要
NOVELTY - Green rubber conductive composites are produced by (a) preparing raw material by (a.1) preparing hydrocolloid/mucilage/gels from Plantago major seeds, (a.2) adding water to microcrystalline cellulose/cellulose powder/granulate to prepare cellulose solution (micro/nanocellulose) or solution in gels; (b) preparing mixture of compounds by (b.1) mixing 10-18 mass% hydrocolloid/mucilage/gel, 30-70 mass% cellulose/micro/nanocellulose solution, and 10-18 mass% graphite or graphene; (c) preparing mixture of compounds by (c.1) mixing 15-25 mass% rubber and 75-85 mass% product obtained in step (b.1); and (d) preparing mixture of the compounds by (d.1) depositing the product obtained in step (c.2) in container, preferably flat, totally smooth, and without physical interferences, (d.2) drying the product at 21-50 degrees C, preferably 25 degrees C, (d.3) heating the oven at 80-120 degrees C, preferably 100 degrees C, to eliminate all moisture from the film/conductive material, and (d.4) obtaining the composites. USE - Production of green rubber conductive composites (claimed) for biomedicine. ADVANTAGE - The green conductive rubber has excellent mechanical and electrical properties. The production process of the composites is highly simple, based on simple mixing of graphene/graphite with latex, cellulose, and hydrocolloid at room temperature. DETAILED DESCRIPTION - Green rubber conductive composites are produced by (a) preparing raw material by (a.1) preparing hydrocolloid/mucilage/gels in two methods, i.e. (a.1.1) Method 1: (i) obtaining granulated/powder/freeze-dried Plantago major seeds, (ii) adding water at 21-80 degrees C, preferably 25 degrees C, for 18 hours, and (iii) obtaining slightly viscous liquid, and (a.1.2) Method 2: (iv) obtaining granulated/powder type Plantago major seeds, (v) adding organic solvent or water at 21-80 degrees C, preferably 25 degrees C, for 18 hours, (vi) distilling seeds for 48 hours, (vii) boiling, filtering, and adding acetone to the product of step (a.1 iii), (viii) drying or lyophilizing the precipitate obtained in step (a.1 iv), (ix) obtaining dry powder/lyophilized mucilage, and (x) adding distilled water to form hydrocolloid/mucilage/gels; (a.2) preparing cellulose solution/microcrystalline cellulose/nanocellulose by (i) adding to microcrystalline cellulose/cellulose powder/granulate the water, at ambient temperature of 50 degrees C, preferably 25 degrees C, (ii) preparing cellulose solution (micro/nanocellulose) or solution in gels in the concentration, preferably 1.5-2.5% (m/v) at 21-50 degrees C, preferably 25 degrees C; (b) preparing mixture of compounds by (b.1) mixing 10-18 mass% hydrocolloid/mucilage/gel, 30-70 mass% cellulose/micro/nanocellulose solution, and 10-18 mass% graphite or graphene (natural or synthetic), preferably natural, until complete homogenization at 21-60 degrees C, preferably 25 degrees C; (c) preparing mixture of compounds by (c.1) obtaining rubber/natural or synthesized latex, (c.2) mixing 15-25 mass% rubber and 75-85 mass% product obtained in step (b.1) until complete homogenization at 21-70 degrees C, preferably 25 degrees C; and (d) preparing mixture of the compounds by (d.1) depositing the product obtained in step (c.2) in container, preferably flat, totally smooth, and without physical interferences, (d.2) drying the product at 21-50 degrees C, preferably 25 degrees C, (d.3) heating the oven at 80-120 degrees C, preferably 100 degrees C, to eliminate all moisture from the film/conductive material, and (d.4) obtaining the composites.
