N,O-羧甲基壳聚糖在导电涤纶织物化学镀中的应用

Application of N,O-carboxymethyl chitosan in conductive polyester fabrics with electroless plating treatment

对壳聚糖引入羧基制备改性N,O-羧甲基壳聚糖(NOCC),因其有良好的水溶性,可采用浸轧法处理在涤纶织物上,利用其在活化过程中吸附贵金属钯引发之后的化学镀,获得致密、均匀的金属镀层,赋予织物导电性和电磁屏蔽效能.采用红外图谱(FT-IR)和13C核磁共振谱图对NOCC进行表征,并用SEM图观察了经NOCC处理后和化学镀后导电涤纶织物的纤维表面形貌.

Chitosan was modified with carboxyl to produce N,O-carboxymethyl chitosan （NOCC）. Due to good water solubility, NOCC was treated on the polyester （PET） fabrics through padding method, which adsorbed precious palladium metal in the activation process and catalyzed the electroless plating process. Accordingly, compact and even metal plating was obtained, which endowed the fabric with electrical conductivity and electromagnetic shielding property. The structure of NOCC was characterized by FT-IR and ^13C-NMR. The morphology of electrical conductive polyester fabric treated by NOCC and electroless plating was observed by SEM.
