| Popis: | In this research, four-types of latex composite films which are carboxymethyl cellulose latex composite film, zeolite latex composite film, microcrystalline cellulose latex composite film and microcrystalline cellulose sodium hydroxide latex composite film were prepared by casting method. Drying time of all films formation is 24 hr. The average thickness of the dry film is 0.10 mm. The transparency of films were measured by UV-Vis spectrophotometer. It was found that the carboxymethyl cellulose latex composite film have more transparency than zeolite latex composite film, microcrystalline cellulose latex composite film and microcrystalline cellulose sodium hydroxide latex composite film respectively. The analysis of functional group of films were measured by ATR-FTIR technique. It was found that all types of films consist of O-H stretching group and C=O group without ether group of cellulose and Si-O-Al group of zeolite. The mechanical property of films were measured by Universal Testing Machine. It was found that the Young’s modulus of microcrystalline cellulose sodium hydroxide latex composite film was higher than microcrystalline cellulose latex composite film, zeolite latex composite film and carboxymethyl cellulose latex composite film respectively. The characteristic of stress-strain curve of films showed that all films were hard and brittle except microcrystalline cellulose latex composite films were hard and tough. |
