以高锰酸钾为氧化剂,浓硫酸和浓硝酸混合配制的混酸作为反应环境,对PAM型碳纤维进行表面改性,然后以改性碳纤维作为经线和纬线织造成织物,经分切得到的一定宽度的基带,接着通过静电吸附上质量分数0.5-3％的碳粉,最终制成改性碳纤维色带.通过红外(FT-IR),x射线衍射(XRD),扫描电子显微镜(SEM)表征了改性前后的纤维特性变化；分别利用Printronix p7010和Printronix p7
本文在不添加还原剂情况下，以PVP为保护剂采用亚临界水热还原制备水溶性纳米银溶胶，并通过UV-Vis光谱实验探索了前驱体、PVP含量、水热反应时间等因素对制备纳米银溶胶的影响.结果表明：[Ag(NH3)2]OH络合离子水溶液是制备纳米银溶胶的高效前驱体；亚临界状态下可有效激发PVP分子中氮原子和氧原子上的孤对电子产生自由电子促使前驱体中Ag+的还原；PVP可有效阻止银粒子间的团聚，当水热反应时间为
