Effect of Electrolyte Impurities within Starch on the Adhesion of Quaternary Ammonium Starch to Fibers

Influences of some electrolyte impurities within starch and starch cationization on the adhesion of quaternary ammonium cornstarch to cotton and polyester fibers were investigated.The electrolytes considered included NaCl,Na2SO4,NaH2PO4 and Na2HPO4.The adhesion to fibers was evaluated in terms of maximum strength and work-to-break of the roving sized with the starch pastes containing electrolytes.It was found that the cationization showed a positive effect on the adhesion to both fibers whereas the electrolytes gave an adverse effect and reduced the adhesion.The adverse effect depends on the type and amount of electrolytes.The influence of electrolytes on the adhesion can be ranked in a series of NaH2PO4 > Na2HPO4 > Na2SO4 > NaCl.The adhesion enhances as the modification extent increases and the electrolyte content decreases.Furthermore,the adverse effect can be compensated by the positive effect of the starch modification even at a low modification extent.If the electrolytes are fully eliminated,the cationic starch can increase the adhesion strength by more than 10% for both fibers.

Synthesis and Characterization of a New Network Polymer Electrolyte Containing Polyether in the Main Chains and Side Chains

1 Results A new network polymer electrolyte matrix with polyether in the side chains and main chains was synthesized by the azo-macroinitiator method and urethane reaction.The macroinitiator,polymer and network polymer were confirmed by Fourier-transform infrared (FT-IR) spectroscopy and 1H NMR.FT-IR was also used to study the environment of lithium ions doped in these network polymer electrolytes.Three important groups are considered: N-H,carbonyl,and ether groups.The thermal properties of the polymer ...     

Electrochemical Study of Conductive Gel Polymer

Conventional ion-conducting polymer consists of electrolyte salt and polymer matrix, so-called salt-inpolymer. It possesses lower conductivity because the migration of ions depends on the motion of polymer segmental. To increase the ionic conductivity, a kind of gel polymer film （GPF） was prepared by in situ polymerization of methyl methacrylate （MMA） monomer in room-temperature ionic liquid （RTIL）, 1-butyl-3- methylimidazolium hexafluorophosphate （BMIPF6）. Due to immeasurably low vapor pressure, high ionic conductivity, and greater thermal and electrochemical stability, BMIPF6 is suitable electrolyte salts for ion-conducting polymer.
