(LB) films were investigated with respect to volatile organic compounds (VOCs)
at room temperature by using Quartz Crystal Microbalance (QCM) method. The
changes in resonance frequency associated with mass changes can be attributed
to the swelling behaviour of copolymer thin films during vapor absorption. </span> <span style="font-size:9pt;font-family:’Palatino Linotype’, serif;">The diffusion coefficients are
found to be 31.07 x 10 <sup>−16 </sup>, 15.61 x 10 <sup>−16 </sup> and 1.22 x 10 <sup>−16 </sup>
cm <sup>2 </sup> s <sup>−1 </sup> for dichloromethane, chloroform, and benzene,
respectively. </span> <span lang="en-gb" style="font-size:9pt;font-family:’Palatino Linotype’, serif;" xml:lang="en-gb">The response of

sensitive to dichloromethane vapor compared to other studied vapors </span> <span style="font-size:9pt;font-family:’Palatino Linotype’, serif;">. </span> <b> <span lang="en-gb" style="font-size:9pt;font-family:’Palatino Linotype’, serif;" xml:lang="en-gb"> </span> </b> </p> <p> <b> </b> </p> <b> </b> <p> <br /> </p>}, number={3}, publisher={Manisa Celal Bayar University}
