摘要

为了使还原氧化石墨烯(rGO)的面内导热方向与复合物材料散热方向一致，提高rGO在复合材料中的导热效率，更大程度地释放rGO的导热潜力，采用冷冻干燥的方法处理rGO的聚酰胺酸(PAA)分散液，得到PAA黏结的rGO三维网络结构，热酰亚胺化之后得到聚酰亚胺(PI)加固的rGO三维网络结构模板(3DrGO-PI). 使用10 wt%的PAA胶液浇铸上述3DrGO-PI模板，制备得到含有rGO三维导热网络结构的3DrGO/PI复合薄膜. 结果表明，所得到的复合薄膜具有良好的导热性能，当rGO的含量为8 wt%时，3DrGO/PI复合薄膜导热系数达到1.57 W·m

Abstract

In this work

high thermal conductive polyimide (PI) composites with reduced graphene oxide (rGO) as filler were prepared. In order to improve the thermal conductivity of rGO in the PI composites

rGO should form heat conductive paths in PI matrix

and the in-plane direction of rGO should be consistent with the heat dissipation direction of composite materials. Therefore

three-dimensional rGO networks (3DrGO) were prepared by freeze-drying technology to construct an effective thermal conductive path in PI matrix. In order to stabilize 3DrGO networks during the preparation process of PI composites

the 3DrGO networks were adhered and reinforced by PI. The process includes: (1) the rGO dispersion containing 3 wt% polyamide acid (PAA) was freeze-dried to prepare the PAA-reinforced 3DrGO network (3DrGO-PAA); (2) the 3DrGO-PAA was treated by thermal imidization to obtain the PI-reinforced 3DrGO network (3DrGO-PI); (3) 10 wt% PAA was cast onto the 3DrGO-PI template and imidized at 100

200

and 350 °C for 1 h

respectively

at each temperature to obtain the 3DrGO-PI/PI composite films. The 3DrGO-PI/PI composite film exhibits the thermal conductivity of 1.57 W·m

with 8 wt% rGO (772% enhancement compared to that of neat PI film). Whereas the PI composite films with random distributed rGO (rGO/PI composite film) or unreinforced 3DrGO (3DrGO-water/PI composite film) only exhibit the thermal conductivity of 0.51 W·m

s of the composite films are slightly enhanced and relatively higher (higher than 390 °C). The coefficient of thermal expansion (CTE) of the composite films can be greatly decreased by the addition of 3DrGO. The CTE of 3DrGO-PI/PI composite film is as low as 2.16 × 10
