- Abstract
In this paper, a large number of hydrogen bonds were constructed between B
4 C particles and poly(vinyl alcohol) (PVA) matrix by means of surface modification to enhance the interaction between the two phases, and highly filled B4 C/PVA fibers and their fabrics were successfully prepared by wet spinning technology, which provided both neutron protection and air- and moisture-permeability. The results show that cetyltrimethylammonium bromide (CTAB) is uniformly coated on the surface of B4 C particles and alkyl tail entanglement with OP-10, which makes the high-filled B4 C particles stable in suspension in PVA spinning solution and stable in spinning process, and the B4 C/PVA fibers and their textile fabrics are obtained with up to 50% filling capacity. Neutron protection and air permeability and moisture permeability of textile fabrics need to be provided 50% wt% B4 C-CTAB-OP-10/PVA fabrics with a single-layer neutron shielding rate of 49.43%. The present work provides a new solution for wearing comfort and radiation protection safety of the products. [ABSTRACT FROM AUTHOR]- Published
