For the synthesis of the copolymer we used sodium alginate (sodium polymanuronate) (Golden Bell® CA, USA) USP grade, ethyl acrylate (EA; Sigma-Aldrich, St. Louis, MO, USA), and as initiator α,α,′-Azoisobutyronitrile (AIBN; Sigma-Aldrich, St. Louis, MO, USA) with a purity of 98%.
For biodegradation tests, we used as a culture medium dextrose and potato agar (DPA BD Bioxon, Edo. de Mex., México), bacteriological agar (BD Bioxon, Edo. de Mex., México), trisodium citrate pentahydrate (Merck, Edo. de Mex., México), monophasic anhydrous potassium phosphate (Merck, Edo. de Mex., México), monobasic anhydrous potassium phosphate (J,T, Baker, Phillipsburg, NJ, USA), copper (II) pentahydrate sulfate (Sigma-Aldrich, St. Louis, MO, USA), manganese sulfate monohydrate, anhydrous orthoboric acid (JT Baker, Phillipsburg, NJ, USA), chloroform (Sigma-Aldrich, St. Louis, MO, USA), magnesium sulfate heptahydrate (Merck), sucrose (Sigma-Aldrich, St. Louis, MO, USA) and glycerol 99.5% purity (Sigma-Aldrich, St. Louis, MO, USA).
The fungus Alternaria spp. isolated in our laboratory was used for the biodegradation.

UV-Cured Poly(Ethyl Acrylate) Films

Check if the same lab product or an alternative is used in the 5 most similar protocols
Films of poly(ethyl acrylate) were obtained by UV polymerization. Briefly, ethyl acrylate (EA; 99%, Sigma-Aldrich) with 2 wt% of ethylene glycol dimethyl acrylate (EGDMA; 98% Sigma-Aldrich) as crosslinker and 1 wt% of benzoin (Scharlab) as initiator were stirred for 15 min at room temperature. Then, the solution was injected between two glass plates separated by a wire of 1.2 mm in diameter, and placed in an ultraviolet oven for 8 h to let the polymerization occur. Subsequent post-polymerization was carried out at 90ºC for 24 h. At that moment films were rinsed for 24 h in boiling ethanol, which was changed every 8 h, to remove residues. Finally, films were dried at room conditions for 24 h, 24 h more under vacuum and under vacuum at 60ºC for 24 extra hours before any ensuing experiment.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
