Provided are a polymer composite material, a rubber composition, and a tire that reversibly change the performance of a tire in response to a temperature change. The present invention relates to a polymer composite material comprising at least one conjugated diene polymer having a weight average molecular weight of 100,000 or more as measured by gel permeation chromatography, the temperature dependence of the water contact angle of the polymer composite material at two temperatures differing by at least 10 DEG C reversibly satisfies the following relational expression (II): the temperature dependence of the contact angle (II): (contact angle at low temperature)/(contact angle at high temperature) * 100 < = 90.
提供了响应于温度变化而可逆地改变轮胎性能的高分子复合材料、橡胶组合物和轮胎。本发明涉及高分子复合材料,所述高分子复合材料由至少一种根据凝胶渗透色谱法测得的重均分子量为100,000以上的共轭二烯聚合物形成,所述高分子复合材料在相差至少10℃的两个温度下的水接触角的温度依赖性可逆地满足以下关系式(II):(II)接触角的温度依赖性:(低温下的接触角)/(高温下的接触角)×100≤90。
