摘要
介绍了金属元素改性酚醛树脂的国内外研究进展。金属元素改性改性酚醛树脂可分为钼改性、钨改性、纳米铜改性等。其中通过纳米金属元素改性,材料的耐热性、韧性可同步得到改善,有较好的发展前景。
In this paper the research progresses for heat resistance of phenolic resin modified by metal elements were summarized.The metal elements modification involved molybdenum modification,tungsten modification.Nano copper modification,etc.Through the noumetal elements modification,the heat resistance and toughness of materials can sync improved,so it may have good prospects for development.
