木质素磺酸钠与PVA共混薄膜的制备与表征OA北大核心CSCDCSTPCD
Preparation and characterization of sodium lignosulfonate/PVA blend films
以木质素磺酸钠(LS)和聚乙烯醇(PVA)为主要原料,添加适量硼砂、明胶在水溶液中溶解共混,流延成膜.通过单因素和正交实验优选了LS/PVA共混膜制备的条件,对共混膜进行了耐水性、形貌、红外、热重、X射线衍射及差示扫描量热分析.结果表明:影响共混膜性能的主要因素有LS含量、硼砂含量以及反应时间,当硼砂含量为2.0%时,共混膜的拉伸强度最大达到43.98 MPa,比纯PVA膜的拉伸强度提高了189;形貌分析表明LS含量影响共混膜两相分散性,适量的明…查看全部>>
With reproducible sodium lignosulfonate (LS) and poly(vinyl alcohol) (PVA) as primary materials, as well as borax and gelatin, a series of blend films were prepared by the film casting method. The process conditions for preparing the blend films with good water-resistance and mechanical properties were determined by single-factor and orthogonal experiments. Water resistance, SEM, FT-IR,TGA, DSC and XRD analysis of blend films were performed to examine the co…查看全部>>
