【摘要】 通过冷冻干燥,将羽毛还原法残渣制成表面光滑、有弹性、孔隙致密、柔韧性高的海绵膜,不需预处理也无需添加交联剂,并通过傅立叶红外光谱仪(FTIR)、扫描电镜(SEM)、元素分析、示差扫描量热仪(DSC)和透气性测量仪对膜进行表征。在最佳甘油含量下,膜均匀平整,在160℃以内性质稳定,透气量368 mm/s,在医药、生物、纺织、环境及日化领域都具有很大的应用潜力。更多还原

【Abstract】 Feather reduction residues were made into a smooth,elastic,porous and flexible sponge film through freeze drying without pretreatment and cross-linking agent.Physical and chemical characters of the sponge were measured with fourier transform infrared spectrophotometry(FTIR),scanning electron microscopy(SEM),elemental analysis,different scanning calorimetri(DSC) and automatic air permeability.Sponge film with the best glycerol content was stable under 160℃,structure densified and uniform,air permeability of 368 mm/s,which could be potentially used in areas of medical science,biology,textile,environmental technology and daily chemicals,etc.更多还原
