Abstract

Gas grafting of cellulose with fatty acid chloride based on chromatogenic chemistry is an effective method which can provide paper with hydrophobic characteristic. In case of gas grafting with fatty acid chloride, various reaction parameters such as concentration of fatty acid chloride, reaction temperature, and reaction time are very important for the optimization of the gas grafting of cellulose. In this study the gas grafting efficiency of PVA (polyvinyl alcohol) coated paper at the various conditions was evaluated by measuring water resistance such as Cobb_1,800 size and water contact angle. Also quantitative analysis was performed for determining reacted or un reacted fatty acid chloride by using ATR spectroscopy and GC. As a result, when the content of palmitoyl chloride esterified with a hydroxyl group at 1% concentration of palmitoyl chloride and 180℃ of react temperature was less than 1 g/m², Cobb_1,800 size degree was less than 10 g/m². And it was found that Cobb_1,800 size value, water contact angle, ratios of absorption peak of 1,735 cm^-1/3,300 cm^-1, amount of grafted fatty acid was improved with increase in concentration of palmitoyl chloride, temperature, and reaction time. And there was good correlation between GC analysis, ATR spectroscopy analysis and Cobb_1,800 sizing degree for evaluation of the grafting efficiency. It should be noted that only water contact angle could not be used to evaluate the grafting efficiency.
