摘要
Abstract
Breathable cellulose membranes were prepared by using NMMO(N-methylmorpholine-N-oxide)technology, through adding CaCO3 particles to the cellulose solution and then removing CaCO3 with acid after the membranes were for-med. The oxygen permeability coefficient and strength properties of the membranes were investigated by controlling the dosage and diameter of CaCO3. The results shows that as the dosage of CaCO3 increases,the oxygen permeability coefficient of the cellulose membranes increases;the tensile strength,the elongation at break and the transparency show a decreasing trend. When the diameter of CaCO3 increases,the oxygen permeability coefficient increases,but the tensile strength and the transparency decreases.关键词
