Introduction (Historical Review),ts followed by linear extension . During the Cold War the U.S. administration showed an interest in producing of microfibrous polymer adsorbents intended for capturing radioactive particles in upper atmospheric layers which were signs of nuclear weapon tests intensively carried out in the U.S.S.R. during those years.
