| 摘要:本研究提出了一种以木质素磺酸钠为原料制备极小尺寸酚醛树脂纳米球(SAFR)的方法,能够实现酚醛树脂纳米材料粒径尺寸在320 nm以内精准调控。通过控制木质素磺酸钠的添加量从0增加到40%,SAFR的粒径从320 nm降低至100 nm内,Zeta电位值高达-49.1 mV,展现出优异的稳定性和抗氧化性能。该纳米球纳米增强效果极为显著:在最优条件下,引入SAFR的PAA水凝胶的拉伸强度高达450.0 kPa,比纯PAA水凝胶增加10.7倍;将SAFR以添加量0.02%添加到PVA材料中,PVA复合膜的拉伸强度增加了4.2倍(达191.4 MPa),断裂伸长率增加了3.9倍(达301.2%)。 |
| Abstract:This study proposed a method for preparing extremely small-sized phenolic resin nanospheres (SAFR) using sodium lignosulfonate as the raw material, enabling precise control over the particle size of phenolic resin nanomaterials within 320 nm. By increasing the addition amount of sodium lignosulfonate from 0 to 40%, the particle size of SAFR nanospheres decreased from 320 nm to within 100 nm, with a Zeta potential value as high as -49.1 mV, demonstrating excellent stability and antioxidant properties. The nano-reinforcing effect of these nanospheres was highly significant: Under optimal conditions, the tensile strength of PAA hydrogel incorporated with SAFR reached up to 450.0 kPa, which was 10.7 times higher than that of pure PAA hydrogel, when SAFR was added to PVA material at a addition amount of 0.02%, the tensile strength of the PVA composite film increased by 4.2 times (191.4 MPa), and the elongation at break increased by 3.9 times (301.2%). |
