Synthesis of silver nanoparticles on bamboo pulp fabric after plasma pretreatment

Silver nanoparticles were synthesized on bamboo pulp fabric with pretreatment of plasma under microwave radiation. The silver nanoparticles coated bamboo pulp fabrics were characterized by Fourier transform infrared spectroscopy, scanning electron microscope, thermogravimetric analysis and X-ray diffraction. Color characteristics and contact angles of silver coated bamboo pulp fabrics were evaluated. Adhesive strength of silver nanoparticles on bamboo pulp fabrics without and with pretreatment of plasma was investigated. Compared with silver nanoparticles coated bamboo pulp fabric without pretreatment of plasma, more silver nanoparticles are coated on the bamboo pulp fabric with pretreatment of plasma. Bamboo pulp fabrics are evenly covered with silver nanoparticles with pretreatment of plasma. In addition, influences of distance between the plasma source and the fabric and treating time on deposition amounts of silver nanoparticles were investigated. Color strength values decrease and increase with the rise of distance and treatment time, respectively. The silver nanoparticles coated bamboo pulp fabric pretreatment of plasma has excellent UV protection, good fastness to laundering and hydrophobicity.
