Abstract

Grafting copolymerization of acrylic acid onto flax fabrics initiated by plasma has been studied. FTIR spectrum indicate that -COO- group in the grafted flax increase. SEM image shows that grafted flax surface is rougher and heavier. The effects of plasma power, initiating time, grafting temperature and monomer concentration on graft yields are investigated. It is found that the flax surface grafting can be optimized by the follwing processing conditions: 200W of plasma power, 150s of initiating time, 60℃ of grafting temperature, and 40% of monomer concentration.
