The polylactide is biodegradable plastic that can be degraded by water and environmental microorganisms. We can offer it different properties using different synthetic factors. Currently, lactic acid is produced from the fermentation of glucose with lactic acid bacteria, then followed by steps of extraction and purification. If lactic acid could be produced from wood base waste material, the producing cost of polylactide will be effectively reduced and wood base waste material will be more valuable.
This study will describe the methodology of isolating glucose from recycled wastepaper, and converting through a series of chemical process to polylactide, then coating polylactide on base paper to produce functional paper, such as waterproof products and disposable utensils. There are three major aspects of investigation, including acid hydrolysis and fermentation of lactic acid, synthesis of polylactide, and manufacturing of polylactide coated paper. In terms of acid hydrolysis, using 72% concentrated sulfuric acid to hydrolyze the recycled waste paper, and the maximum yield of glucose is about 81%. Then fermentation of these sugars to lactic acid with bacteria, Lactobacillus paracasei subsp. pracasei. Each mole of glucose can produce 1.87 mole lactic acid. In terms of polylactide synthesis, using direct polymerization and ring opening polymerization,. The results indicated that the optimal condition of the direct polymerization method is lactic acid added 0.3% stannous octoate at 190 ℃ for 24 hours. The best distribution of average molecular weight of polylactide can be obtained under this condition, and the molecular weight is 12,248. On the other hand, with ring-opening polymerization method, lactic acid was added 0.3% stannous octoate at 150℃ for 12 hours, and more than 44,730 molecular weight of polylactide were obtained. In terms of manufacturing of polylactide coated paper, using two coating methods, one is solution coating method and the other is polylactide particles with PVA as coating binder method. The results indicated that when paper were coated with PVA as coating binder, the tensile strength of coated paper can be improved about 20% with the molecular weight 10,000 of polylactide and the coating amount of 8 g/㎡. It also effectively improve the elongation about 40%, the retention of wet tensile strength is more than 60%. And the water absorption of Cobb test of PLA coated paper was from 30.21 g/㎡ down to 10.03 g/㎡ after coating , it showed that water resistant properties were greatly improved.
