亲水基团性质对双亲性壳聚糖衍生物单分子膜性能的影响
Effect of hydrophilic group on monolayer propertie ofN,N-dilauryl chitosan derivatives
摘要
Abstract
O-sulfonated-N,N-dilauryl chitosan(HSDLCS),O-quaternized-N,N-dilauryl chitosan (QADLCS) andO-hydroxypropyl-N,N-dilauryl chitosan(HPDLCS) with similar substitution were synthesized. The effect of hydrophilic group on monolayer properties ofN,N-dilauryl chitosan derivatives was studied. Experimental results indicated thatmonolayers of N,N-dilauryl chitosan derivativeswith different hydrophilic group had larger collapse pressure(πc) and maximum compression modulus (Cs−1,max) compared withN,N-dilauryl chitosan and also had better cohesion. Inonic products had larger collapse pressure(πc) and maximum compression modulus (Cs−1,max) compared with nonionic product HPDLCS. Anionic HSDLCS monolayer had largestπc(44.64mN/m) andCs−1,max(84.27mN/m)among three products,and cationic QADLCS had second largestπc(42.01mN/m) andCs−1,max(82.99mN/m). HSDLCS monolayer had stronger cohesion and resistance to deformation capacity.关键词
