Density changes in very thin films of DPMMA as seen by neutron critical reflection

We present some preliminary evidence on the variation of polymer density with film thickness. Our studies are still at an early stage but nevertheless our results point out strongly the necessity of considering interfacial effects when thin films are involved. We studied the influence of annealing o...
