摘要/Abstract

摘要： 以聚L-乳酸(PLLA)和麦草(WS)为原料,以N-甲基吗啉-N-氧化物(NMMO)为溶剂,采用溶液共混法制备了PLLA/WS共混物。首先将麦草溶解在NMMO后,再添加聚L-乳酸并溶解,制备聚L-乳酸与麦草的共混溶液。共混溶液采用浇膜法制备PLLA/WS共混物,采用差示扫描量热法、X射线衍射法、傅里叶变换红外光谱、热重分析和扫描电镜等方法对所得的共混物进行表征。结果表明,聚L-乳酸与麦草可以形成均匀的共混溶液。共混物中PLLA与麦草组分之间具有较强的相互作用,相容性较好。当共混物中PLLA的质量分数为50%时,共混物可以形成结晶结构,且随着PLLA 含量的增加,其结晶更加完美,熔点与热稳定性提高。共混物薄膜断面结构较为致密,这说明PLLA与麦草相容性较好,混合均匀。通过调节聚L-乳酸和麦草的配比,可以制备不同性能的生物高分子材料。

关键词: 聚L-乳酸, 麦草, 共混物, 相容性

Abstract: The blends of PLLA/WS were prepared using poly(L-lactic acid)(PLLA) and wheat straw(WS) in N-methyl morpholine-N-oxide(NMMO)solution.WS was firstly dissolved in NMMO,then PLLA was successively dissolved in the WS solutions to get homogeneous mixture solutions.The mixtures were cast to prepare PLLA/WS blends.Differential scanning calorimetry,X-ray diffraction,Fourier transform infrared spectroscopy,thermogravimetry,and scanning electron microscopy were employed for the characterization of the blends.The results showed that PLLA and WS could form a homogeneous mixture in NMMO.A strong interaction between PLLA and WS was observed.The crystal structures were formed as the PLLA content was under 50%.With the increase of PLLA contents,the thermostability and melting points of PLAA/WS were gradually increased.The blend films possessed smooth section and micropore due to the compatibility between PLLA and WS.The biodegradable polymeric materials with different properties could be prepared through modifying the ratios of PLLA to WS.

Key words: poly(L-lactic acid), wheat straw, blend, compatibility
