  • 简介:环境友好thermosettingcomposites被作为矩阵混合小麦面筋(WG)准备,钙碳酸盐(CaCO3)由在120掳C塑造混合到交叉连接的压缩作为可塑剂作为filler和甘油列在后面WG矩阵。形态学观察证明CaCO3粒子细微地在矩阵被驱散。直到进composites的10wt%的CaCO3的加入引起了幼仔的模量和张力的力量显著地增加。在另一方面,在裂缝的潮湿吸收和延伸稍微减少了。

  • 简介:Polyaniline(平底锅)敏化nanocrystallineTiO2composites(TiO2/PAn)成功地被准备并且为染料甲又蓝色(MB)的降级用作有效光催化剂。结果证明那个平底锅能高效地敏化TiO2,合成光催化剂能被两个都吸收紫外、可见的光激活(λ:190800nm),而纯TiO2仅仅吸收了紫外光(λ<380nm)。在自然的光的照耀下面,MB能比在TiO2上在TiO2/PAncomposites上更高效地被降级。而且,它能被简单沉积容易与答案分开。
